Fixes <https://bugs.gnu.org/46737>. PostgreSQL running with a different socket directory to the default one in the package itself breaks some services, this commit restores the previous behaviour where PostgreSQL by default will run with a socket directory that matches the default used by PostgreSQL packaged for Guix. Switching to a different default value can happen, but only alongside changing the PostgreSQL package. * gnu/services/databases.scm (<postgresql-config-file>)[socket-directory]: Change default to #false. * doc/guix.texi (Database Services): Update documentation, and specify a different value for disabling connections via sockets. * gnu/tests/guix.scm (%guix-data-service-os): Use default PostgreSQL behaviour. * gnu/tests/monitoring.scm (%zabbix-os): Likewise. * gnu/tests/web.scm (patchwork-os): Likewise.
