Yes. PostgreSQL bugs do not belong here, report them to the PG developers instead. Previous Comments: ------------------------------------------------------------------------ [2005-07-06 13:58:07] vda at ilport dot com dot ua I've seen several vague bug reports here "PHP eats lots of mem with PostgreSQL" but none was researched in any depth. I thought I can spend at least ten minutes at it. Also I wanted to have an URL where this bug is reported. Apparently PostgreSQL team does not have bugzilla. I reported the issue to PostgreSQL team also using http://www.postgresql.org/support/submitbug, repeating bug report and also gave then URL to this page. Did I do something wrong? ------------------------------------------------------------------------ [2005-07-06 13:39:29] [EMAIL PROTECTED] >I think this is a problem with PostgreSQL client libs. Please explain: you think that this is a problem with PG client libs and you're reporting it in PHP bug system? ------------------------------------------------------------------------ [2005-07-06 13:19:28] vda at ilport dot com dot ua Description: ------------ Seen on php-4.3.4RC2. Since I was just testing how good PG fares compared to Oracle, and I am not feeling any real pain from this (IOW: not my itch to scratch), I do not research this in depth, apart from submitting bug report. Sorry. Symptom: even the simplest query $result = pg_query($db, "SELECT * FROM big_table"); eats enormous amounts of memory on server (proportional to table size). I think this is a problem with PostgreSQL client libs. php's source is included for easy reference. PHP_FUNCTION(pg_query) { ... pgsql_result = PQexec(pgsql, Z_STRVAL_PP(query)); if ((PGG(auto_reset_persistent) & 2) && PQstatus(pgsql) != CONNECTION_OK) { PQclear(pgsql_result); PQreset(pgsql); pgsql_result = PQexec(pgsql, Z_STRVAL_PP(query)); } if (pgsql_result) { status = PQresultStatus(pgsql_result); } else { status = (ExecStatusType) PQstatus(pgsql); } switch (status) { case PGRES_EMPTY_QUERY: case PGRES_BAD_RESPONSE: case PGRES_NONFATAL_ERROR: case PGRES_FATAL_ERROR: php_error_docref(NULL TSRMLS_CC, E_WARNING, "Query failed: %s.", PQerrorMessage(pgsql)); PQclear(pgsql_result); RETURN_FALSE; break; case PGRES_COMMAND_OK: /* successful command that did not return rows */ default: if (pgsql_result) { pg_result = (pgsql_result_handle *) emalloc(sizeof(pgsql_result_handle)); pg_result->conn = pgsql; pg_result->result = pgsql_result; pg_result->row = 0; ZEND_REGISTER_RESOURCE(return_value, pg_result, le_result); } else { PQclear(pgsql_result); RETURN_FALSE; } break; } } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33587&edit=1
