pg_hint_plan adds PostgreSQL 19 support and parser fixes

pg_hint_plan lets PostgreSQL users influence execution plans through hints in SQL comments. Version 1.9.0 adds PostgreSQL 19 compatibility and support for path generation strategies. Companion maintenance releases address issues including a multi-query hint-parser loop and a server crash during error handling. Choose the extension version matching your PostgreSQL major release; 1.9.0 is not the universal upgrade for every installation.

More context

Review the matching release notes and test affected queries before upgrading. The announcement also says this is the last planned release for PostgreSQL 14.

Keep in mind

Plan hints require workload-specific testing; the announcement does not promise faster execution for every query.
