KentarouTakeda 5f1a92089f ext/pgsql: Update outdated PostgreSQL version requirements (#5409) ...

## 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outdated for years.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`.
