Evict cached statements on schema change for tables with 10+ columns - #1754

…clipse-vertx#1752) See eclipse-vertx#1751 Motivation: TABLE_SCHEMA_CHANGE_ERROR_MESSAGE_PATTERN matched the column counts with \d, a single digit, and String.matches requires a full match. So "bind message has 10 result formats but query has 11 columns" never matched, the stale cached statement was never evicted, and every later execution on the connection failed with the same error until the connection was closed. Postgres reports this error when a proxy such as RDS Proxy parses the named statement again after the schema change, before the client binds. Modifications: Match the column counts with \d+ and precompile the pattern. Add a test that uses a 10-column table, adds an 11th column, and re-prepares the named statement with DEALLOCATE / PREPARE to simulate the proxy. Result: The cached statement is evicted after the first failure, and the next execution succeeds.
