Fix all postgresql server commands in launchctl wrappers and installation notes

[toy]

Description

Wrappers created for postgresqlNN-server before 16 use su instead of sudo to execute as postgres, but postgres has shell set to /usr/bin/false, so su commands fail. See https://trac.macports.org/ticket/68412 which fixed it for postgresql16-server and #14331 which fixed it for postgresql96-server.

While resolving build errors (following a nudge from @barracuda156):

• Removed dependency of postgresql96-server on bash
• Switched all postgresqlNN to use PortGroup openssl with branch 1, 1.1 or 3
• Added patches to fix int64 checks (failing due to usage of exit function without header) and usage of incompatible function in xml.c (without const qualifier where one is expected, it apparently switched by default from a warning to an error in osx 14)
• All versions compile succesfully on intel (osx13 runner), but versions <= 9.1 fail on amd (osx14 and osx15 runners) with errors:
  • clang: error: unsupported option '-mthreads' for target 'arm64-apple-darwin23.6.0' for <= 9.0
  • ../../../../src/include/storage/s_lock.h:937:2: error: PostgreSQL does not have native spinlock support on this platform. To continue the compilation, rerun configure using --disable-spinlocks. However, performance will be poor. Please report this to pgsql-bugs@postgresql.org. for 9.1

spinlock problem can probably be fixed by adding handling for arm64 as in 9.2 and problems with threads I didn't look into, but I would prefer to leave it for now

Failures are due to failing to install dependencies for older versions, most if not all are already marked as known to be failing

Just nobody bothered to fix them after breaking by openssl default version change. They should use openssl PG with 1.0 branch, as I recall. Not a path to openssl.dylib, which pick an incompatible 3.0. Maybe a few minor tweaks to the portfile. Last time when I needed some old postgresql9x, it did not take much to fix the build.

Thank you for the build fixes
