[php-src] Issue #12685: PGSQL pipeline mode constant PGRES_PIPELINE_ABORTED not found and naming problem

Issue: https://github.com/php/php-src/issues/12685 Author: degtyaryov ### Description Hello! The following code: ```php <?php $is_aborted_pipeline_status = (pg_pipeline_status($connection) === PGSQL_PIPELINE_ABORTED); // PQ_PIPELINE_ABORTED $is_aborted_result_status = (pg_result_status($result) === 11); // PGRES_PIPELINE_ABORTED ``` In libpq exists two constant: ``` PQ_PIPELINE_ABORTED = 2 PGRES_PIPELINE_ABORTED = 11 ``` In php naming constant rules: ``` PQ_* -> PGSQL_* PQRES_* -> PGSQL_* ``` Need add constant PGRES_PIPELINE_ABORTED in PHP! The absence of a second constant in IDE autocompletion leads to unobvious errors. ### PHP Version PHP 8.3 ### Operating System _No response_
