postgresql: support JIT #150801

Commits on Dec 18, 2021

  1. postgresql: recurse in the derivation itself 

    This both makes the code cleaner and allows for expressions like:

`(postgresql.override { jitSupport = true; }).pkgs.postgis`

The change also allows users to configure PostgreSQL flags in NixOS
module more conveniently:

```
{
  services.postgresql.package = pkgs.postgresql.override { jitSupport = true; };
  services.postgresql.extraPlugins = with config.services.postgresql.package.pkgs; [ postgis pg_repack ];
}
```

Before they were required to override `postgresql` in an overlay or
pass `this` explicitly.

  2. postgresql: support JIT 

    Disable it by default because of closure size, and to avoid surprise
negative performance changes in production (were observed with very
large and complex queries due to compilation time).

See also dcd9455 for a great
explanation on how JIT interacts with packaging and closure size.
