Changelog:

  * Added support for PostgreSQL 18, upcoming Postgres Extended 18,
    and upcoming EDB Postgres Advanced Server 18.

  * Improved the handling of "NULL" values when executing parameterized
    queries or execution-timed parameters to prevent unpredictable behavior due
    to dangling pointers.

  * Changed behavior where internal parameters were pushed to the remote
    server, which could cause the server to crash. Internal parameters are no
    longer pushed to the remote server.

  * Remove support for PostgreSQL 12, Postgres Extended 12, and EDB Postgres
    Advanced Server 12.
