## Summary The pgsql extension documentation references PostgreSQL versions that have been outdated for years. The requirements page (`reference/pgsql/setup.xml`) states: https://www.php.net/manual/en/pgsql.requirements.php > To use PostgreSQL support, you need PostgreSQL 6.5 or later, > PostgreSQL 8.0 or later to enable all PostgreSQL module features. However, the actual minimum libpq versions enforced by php-src are: | PHP version | Minimum libpq | Commit | |---|---|---| | PHP 8.0+ | libpq 9.1 | php/php-src@ce668c0ec6 | | PHP 8.4+ | libpq 10.0 | php/php-src#14628 | The "PostgreSQL 6.5" requirement has been incorrect since at least PHP 8.0.0 (released 2020-11-26), which requires libpq 9.1 via `PQlibVersion` check in `ext/pgsql/config.m4`. As of PHP 8.4, the minimum was further raised to libpq 10.0 via `PQencryptPasswordConn` check in `build/php.m4`. ## Changes - **setup.xml**: Update requirements to match php-src, following the same pattern used by ext/curl and ext/openssl (per-PHP-version listing). - **14 function pages**: Remove notes referencing PostgreSQL versions 6.3–9.0 that are no longer relevant given the libpq 10.0 minimum. These include version-gated notes for `pg_prepare`, `pg_query_params`, `pg_execute`, `pg_escape_string`, `pg_escape_identifier`, `pg_escape_literal`, `pg_client_encoding`, `pg_unescape_bytea`, `pg_result_error_field`, `pg_parameter_status`, `pg_lo_create`, `pg_version`, `pg_affected_rows`, and the general `reference.xml`.

Looks up a current parameter setting of the server.

</para>
|
|
<para>
|
|
Certain parameter values are reported by the server automatically at
|
|
connection startup or whenever their values change. <function>pg_parameter_status</function> can be
|
|
used to interrogate these settings. It returns the current value of a
|
|
parameter if known, or &false; if the parameter is not known.
|
|
</para>
|
|
<para>
|
|
Parameters reported by the server include <literal>server_version</literal>,
|
|
<literal>server_encoding</literal>, <literal>client_encoding</literal>,
|
|
<literal>is_superuser</literal>, <literal>session_authorization</literal>,
|
|
<literal>DateStyle</literal>, <literal>TimeZone</literal>, and <literal>integer_datetimes</literal>.
|
|
Note that
|
|
<literal>server_version</literal>, <literal>server_encoding</literal> and <literal>integer_datetimes</literal>
|
|
cannot change after PostgreSQL startup.
