conflicting flags; update any section control definitions (the objects that have
properties 'deps' and 'disabled'—e.g., the section controls grouping under 'Type
of objects' that currently list deps like
['pre_data','data','post_data','only_data','only_schema','only_tablespaces','only_roles'])
to include 'only_statistics' in their deps arrays and add the corresponding
check in their disabled predicate (i.e., include state.only_statistics in the OR
chain used in disabled functions); make the same symmetric change in the restore
schema file where the section controls are defined so both backup and restore
honor the only_statistics switch.

Three issues:
--no-statisticsis added to restore but missing from backup. The PG18 release notes introduce--no-statisticsforpg_dump/pg_dumpallalongside--statistics/--statistics-only. Restore exposes "Do not restore statistics" but backup has no matching "Do not dump statistics" — inconsistent and a feature gap. Addset_param('no_statistics', '--no-statistics', manager.version >= 180000)plus the corresponding UI field withmin_version: 180000.- Backend mutex missing for
only_statistics. The existingonly_data/only_schemapair has backend mutual-exclusion (e.g.only_schemaskipped ifonly_datais set), butonly_statisticshas no such guard. A direct POST with{"only_data": true, "only_statistics": true}will emit both flags andpg_dumpwill reject. UI handles it viadisabledfunctions, but the backend pattern is inconsistent. Sameassertionpattern asonly_schemais the fix. - "Unit" tests aren't unit tests.
test_backup_create_job_unit_test.pyusesserver_utils.connect_server()and a realself.server_information['server_version'], so PG18 scenarios are silently skipped on any CI without a live PG18 instance. The version-gate logic is never exercised by a mock. Worth adding a trueMagicMocktest withmanager.version = 170000asserting the PG18 flags are absent — applies to all six new options.
Confirmed correct: all six flags are genuinely new in PG18, version gate at 180000 is right, args passed as a list (no shell injection surface), gettext() wrapping present.

Adds the new pg_dump/pg_dumpall/pg_restore options introduced in PostgreSQL 18, gated to servers >= 18: - Only statistics (--statistics-only) in Type of objects, mutually exclusive with the other Only * switches. - Row security policies (--no-policies), Data (--no-data) and Schema (--no-schema) in Do not save (both dialogs); Statistics (--no-statistics) in the Restore dialog. - Dump statistics (--statistics) and Sequence data (--sequence-data) in Backup Miscellaneous. The pg_dumpall -F/--format option and the pg_restore --exclude-database / -g/--globals-only options are not included: the non-text pg_dumpall feature was reverted before PostgreSQL 18.0 and those options do not exist in the shipped 18.x client utilities. Includes backend arg-builder wiring, unit-test scenarios and docs. Closes pgadmin-org#9064 Closes pgadmin-org#9065 Closes pgadmin-org#9066
pg_dump and pg_dumpall both accept --no-statistics, but only the Restore dialog offered it, so the Backup dialogs could dump statistics or nothing but statistics whilst having no way to say "everything except statistics". Backup now has the matching Statistics switch under Do not save, documented alongside the others. The larger problem is that several of these options cannot be combined, which I checked against the shipped utilities rather than inferring: pg_dump 18 reports "options -s/--schema-only and --statistics-only cannot be used together", and likewise for --data-only with --statistics-only, --statistics-only with --no-statistics, --schema-only with --no-schema and --data-only with --no-data. pg_restore and pg_dumpall reject the same pairs. The dialog disabled some of those combinations and not others, and nothing stopped a request arriving with both halves set, in which case the utility rejected the whole command. The backend now suppresses the narrower option in each pair, following the pattern --schema-only already used, and the switches under Do not save follow the state of their matching Only switch in both dialogs. The tests for the v18 options previously only ran where a v18 server was available, and silently skipped otherwise, so the new test_*_pg18_args_unit_test.py files call the argument builders directly with a mocked manager version. They cover the options being emitted on 18, suppressed on 17, and each conflicting pair resolving to the wider option. One existing scenario asserted a command pg_restore would have rejected, setting both --statistics-only and --no-statistics, so it is now split into two.
…s with
pg_dump and pg_dumpall 18 reject --statistics alongside --data-only,
--schema-only or --no-statistics ("options -a/--data-only and --statistics
cannot be used together" and so on, checked against 18.6), but the
Dump statistics switch was never disabled and the arg builder emitted it
unconditionally, so those combinations produced a command the utility
refused. The builder now drops --statistics in each case, which gives the
result the other option asked for since statistics are not dumped by
default, and the dialog disables Dump statistics and Do not save
Statistics against each other and the Only data/schemas switches.
--statistics with --statistics-only is accepted, so that pair is left
alone.

pg_dump,pg_dumpallandpg_restore18 reject--statistics-onlywith--data-only/--schema-only, each--no-*option with its matching--*-onlyoption, and--statisticswith--data-only,--schema-onlyor--no-statistics. The dialogs disable those combinations, and the argbuilders also drop the narrower option so a request with both set cannot
produce a command the utility would reject.
Note on options that are not included
The
pg_dumpall -F/--formatoption (requested in #9065) and thepg_restore--exclude-database/-g/--globals-onlyoptions (requested in #9066) arenot added: the non-text
pg_dumpallfeature was reverted beforePostgreSQL 18.0, and those options do not exist in the shipped 18.x client
utilities (verified against
pg_dumpall --help/pg_restore --helpon18.4). The remaining, real PG 18 options from those issues are included.
Testing
test_backup_pg18_args_unit_test.pyandtest_restore_pg18_args_unit_test.pycall the arg builders with a mocked
manager.version, covering the flagsbeing emitted on 18, suppressed on 17, and each conflicting pair; the
create-job tests also gained v18 scenarios for a live 18 server.
