To use PostgreSQL support, you need libpq (the PostgreSQL C client

library).

As of PHP 8.0.0, libpq 9.1 or later is required.

As of PHP 8.4.0, libpq 10.0 or later is required.

PostgreSQL supports many character encodings including

multibyte character encoding. The current version and more

information about PostgreSQL is available at

<link xlink:href="&url.pgsql;">&url.pgsql;</link> and

the <link xlink:href="&url.pgsql.manual;">PostgreSQL Documentation</link>.
