When used as a global override, it breaks most of the options in the
mysql module, such as ensureDatabases, ensureUsers, initialDatabases,
initialScript.
We could use `.client` there, but if the reasoning behind this was
closure size reduction, we now end up with the same (or a bigger)
runtime closure and more complexity.
Apart from the options exposed by the mysql module, the client is also
likely to be required for local backups or DBA tasks anyways.
Instead of dealing with all the increased complexity of this for no
arguable benefit, let's just remove the `withoutClient` argument.
Storage space on mysql servers shouldn't be that much of an issue.
Closes#82428.
* nixos/postgresql: support 0750 for data directory
This is rework of part of https://github.com/NixOS/nixpkgs/pull/46670.
My usecase was to be able to inspect PG datadir as wheel user.
PG11 now allows starting server with 0750 mask for data dir.
`groupAccess = true` now does this automatically. The only thing you have to do
is to set group ownership.
For PG10 and below, I've described a hack how this can be done. Before this PR
hack was impossible. The hack isn't ideal, because there is short
period of time when dir mode is 0700, so I didn't want to make it official.
Test/example is present too.
* postgresql: allow changing initidb arguments via module system
Closes https://github.com/NixOS/nixpkgs/issues/18829
+ some cleanups
* addressed review comments and some fixes
* whoops
* change groupAccess to tristate, to not force `chmod` on dataDir.
Making mask either 0700 or 0750 is too restrictive..
* WIP
* let's not support group mode for versions pre-11.
The only fix is to change mode to 0700 before start, because otherwise postgresql
doesn't start, and error is non-obvious.
The following error was printed every second:
Can't exec "clear": Not a directory at /nix/store/.../bin/.mytop-wrapped line 110.
Use of uninitialized value $CLEAR in string at /nix/store/.../bin/.mytop-wrapped line 781.
Therefore the mytop output was repeatedly displayed instead of updating itself "in-place".
