Wiki / Configuration Parameters

debug_print_rewritten

These parameters enable various debugging output to be emitted. When set, they print the resulting parse tree, the query rewriter output, or the execution plan for each executed query. These messages are emitted at LOG message level, so by default they will appear in the server log but will not be sent to the client. You can change that by adjusting client_min_messages and/or log_min_messages. These parameters are off by default.

English manual coverage begins with PostgreSQL 7.4. Source history and runtime observations have their own recorded version boundaries.
