Hello,

Here's a patch to improve PostgreSQL service. It merges
<postgresql-configuration> and <postgresql-config-file> records. It also
sanitises parameters conversion and logging.

Thanks,

Mathieu

Subject: [PATCH] Improve PostgreSQL service.

Merge <postgresql-configuration> and <postgresql-config-file> records,
sanitize parameters convertion and logging.

postgresql-config-file?, postgresql-config-file-log-destination,
postgresql-config-file-hba-file, postgresql-config-file-ident-file,
postgresql-config-file-extra-config, postgresql-configuration): Remove them.

postgresql-configuration-hba-file,
postgresql-configuration-ident-file,
postgresql-configuration-socket-directory,
postgresql-configuration-extra-config,
postgresql-configuration-extension-packages): New exported procedures.
(<postgresql-config-file>): Merge it with ...
(<postgresql-configuration>): ... this record, and add a "socket-directory"
field.
(postgresql-config-file-compiler): Replace it with ...
(postgresql-config-file): ... this procedure.
(postgresql-activation): Use "match-record" instead of "match". Create the
"socket-directory" if needed.
(postgresql-shepherd-service): Use "match-record" intead of "match". Pass the
"log-destination" argument to "pg_ctl" if needed.
(postgresql-service): Remove it.
* gnu/tests/databases.scm (%postgresql-log-directory): New variable.
(%postgresql-os): Pass "log-destination" and "extra-config" fields.
(log-file): New test case.
* gnu/tests/guix.scm (%guix-data-service-os): Adapt accordingly.
* doc/guix.texi (Database Services): Ditto.
