A configuration parameter controlling warnings about operator precedence changes
This entry relates to a PostgreSQL feature which is deprecated and may be desupported in future releases.

operator_precedence_warning is a configuration parameter controlling whether warnings about operator precedence changes should be emitted.

operator_precedence_warning was added in PostgreSQL 9.5 and removed in PostgreSQL 14.


Default value for operator_precedence_warning is: off.


operator_precedence_warning was intended to assist debugging for applications affected by changes to operator precedence in PostgreSQL 9.5 to match the SQL standard (commit c6b3c939).

It was not intended for use in production environments.
