Config this extension to shared_preload_libraries:

shared_preload_libraries = 'pg_query_rewrite';

Create this extension with:

CREATE EXTENSION pg_query_rewrite;

Usage

Source: README

pg_query_rewrite rewrites an exact source SQL statement into a predefined target statement using rules stored in shared memory.

Required setup 

-- postgresql.conf
shared_preload_libraries = 'pg_query_rewrite'
pg_query_rewrite.max_rules = 10

CREATE EXTENSION pg_query_rewrite;

Rule management 

SELECT pgqr_add_rule('select 10;', 'select 11;');
SELECT pgqr_rules();
SELECT pgqr_remove_rule('select 10;');
SELECT pgqr_truncate();
  • pgqr_add_rule(source, target): add a rewrite rule.
  • pgqr_remove_rule(source): remove one rule.
  • pgqr_truncate(): remove all rules.
  • pgqr_rules(): inspect current shared-memory rules and rewrite counts.

Caveats

  • Matching is exact: case, whitespace, and semicolons must match character-for-character.
  • Parameterized SQL is not supported.
  • Maximum statement length is hard-coded at 32 KB.
  • Rules are not persisted; they vanish on restart unless you reapply them.
