build problems when multiple postgresql versions are installed

[anneb]

When multiple postgresql versions are installed, it seems you can only build for the newest version.
Did I overlook something obvious?

I found the following last/newest(?) installed postgresql version dependent settings:

files:
debian/rules:

  PGVERSION=`pg_buildext supported-versions $(CURDIR) | tail -l` || exit $$?;

Makefile:

  EXTDIR=$(shell pg_config --sharedir)

icutranslit/Makefile
pg_config is used twice (always linked to newest or last installed version?)

kanjitranscript/Makefile
pg_config is used twice

I was able to build for other versions as follows:
file debian/pgversions
replace 9.6+ by version number you wish to build for, example: 12

file Makefile:

PGVERSION=12
PG_CONFIG=/usr/lib/postgresql/$(PGVERSION)/bin/pg_config
EXTDIR=$(shell $(PG_CONFIG) --sharedir)

file icutranslit/Makefile

PGVERSION=12
PG_CONFIG=/usr/lib/postgresql/$(PGVERSION)/bin/pg_config
PGPATH=$(shell $(PG_CONFIG) --includedir-server)
...
install -D -m 644 osml10n_translit.so $(DESTDIR)$(shell $(PG_CONFIG) --pkglibdir)/osml10n_translit.so

file kanjitranscript/Makefile

PGVERSION=12
PG_CONFIG=/usr/lib/postgresql/$(PGVERSION)/bin/pg_config
PGPATH=$(shell $(PG_CONFIG) --includedir-server)
..
install -D -m 644 osml10n_kanjitranscript.so $(DESTDIR)$(shell $(PG_CONFIG) --pkglibdir)/osml10n_kanjitranscript.so

now I was able to override the postgres version number as follows:

1. update the version number in debian/pgversions to XX
2. make PGVERSION=XX deb
   where XX is the version number you want to build for.

Thanks @anneb , that actually works! There should really be a way to do this out of the box. Easy enough to add support for PGVERSION in the Makefiles, but any idea what to do with debian/pgversions?

Just to make sure that this is known:
I am currently working at deprecating this approach altogether
