continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
This is needed because some PostgreSQL plugins don't have a bin
directory. If only these plugins are listed in cfg.extraPlugins buildEnv
will turn $out/bin into a symbolic link to ${pg}/bin. Lateron we try to
rm $out/bin/{pg_config,postgres,pg_ctl} which will then fail because
$out/bin will be read-only.
This is a backwards compatible change; it mostly puts all the extensions
for postgresql in a common directory to keep them isolated.
It also moves a few things that /were not/ extensions out into other parts of
the filesystem namespace; namely the postgresql_jdbc and psqlodbc libraries
were moved under development/java-modules and development/libraries,
respectively. Because these libraries use the libpq postgresql client drivers,
they're less sensitive to underlying version changes anyway (since the protocol
is relatively stable).
No attributes were renamed or harmed in the creation of this patch.
