Stdlib: pgsql legacy aliases (pg_exec/pg_numrows/…) missing after modern names (ext/pgsql/pgsql.c) #22219
Description
Category

Problem
Zend ext/pgsql still registers legacy aliases for older PHP/pgsql spellings (pg_exec, pg_numrows, pg_cmdtuples, pg_fieldname, lo_* short names, …). php-compiler already implements the modern names (pg_query, pg_num_rows, pg_affected_rows, pg_field_name, pg_lo_open, …) but aliases are absent (function_exists false on VM; true on Zend 8.2+ with pgsql). Sibling pattern: openssl alias fix #20306 / stream aliases #20903.

Legacy code and PEAR-era scripts call the old names; they must resolve to the same handlers as Zend.
php-src reference
- php/php-src
ext/pgsql/pgsql.stub.php— alias declarations (pg_exec→pg_query, etc.) - php/php-src
ext/pgsql/pgsql.c—PHP_FALIAS/ stub aliases
PHP implementation target
ext/pgsql/Module.php— register aliases pointing at existing Internal classes (same pattern as other ext alias registrations)- Do not duplicate execute bodies; one handler, two names
- Confirm
get_defined_functions()/function_exists/ reflection name match Zend alias reporting
Repro
./script/docker-exec.sh -- bash -lc 'php bin/vm.php -r '"'"'
foreach (["pg_exec","pg_query","pg_numrows","pg_num_rows","pg_cmdtuples","pg_affected_rows"] as $f) {
echo $f, "=", function_exists($f) ? "Y" : "N", "\n";
}
'"'"''
# compare with host php -r '…'Done when
- All listed aliases
function_existstrue and invoke the modern implementations - Compliance / unit alias existence table (no live DB required)
- php-src-strict; no php-compiler-strict shortcut
