Changes proposed in this pull request:

• Fix postgres version regex

In GitHub actions, Postgres version changed from:

psql (PostgreSQL) 14.9 (Ubuntu 14.9-1.pgdg22.04+1)

to

psql (PostgreSQL) 14.10 (Ubuntu 14.10-1.pgdg22.04+1)

PostgreSQL minor version can have more than 1 digits. Hence, changed regex from \d to \d+ (here, 9 to 10).
