Description:

I try
1) add in Makefile
CONTRIB_TESTDB = postgres
2) add in Makefile
REGRESS_OPTS = --use-existing --dbname=postgres
3) add in Makefile
EXTRA_REGRESS_OPTS = --use-existing --dbname=postgres
4) before calling make installcheck
export CONTRIB_TESTDB=postgres
but results everything is same:
/usr/lib/postgresql/pgxs/src/makefiles/../../src/test/regress/pg_regress
--inputdir=./ --bindir='/usr/bin'    --use-existing --dbname=postgres
--dbname=contrib_regression extension
i.e. pgxs places --dbname=contrib_regression in last option due to

Indeed.

Doesn't it work to set that after including the global Makefile?
I thought make's rule was last-one-wins.  Another thing worth
experimenting with is to set it using ":=" rather than "=".

Also, it should work to override it from the command line, viz

      make check CONTRIB_TESTDB=foo

although I gather the OP wants to set it in his own Makefile.
