Subject: [PATCH] build: adjust configure for postgresql 10/11

The openSUSE PostgreSQL 11 no longer ships the pg_config program.
Instead, there exists a .pc file (likewise in pg10), so make use of
that, by default.

The old --with-pgsql-inc and --with-pgsql-lib option are going away
and replaced by the standardized mechanisms pkg-config.m4 has in
store for when there is no .pc file or an unusual location:

	./configure --with-pgsql pgsql_CFLAGS="-I/opt/pgsql/include" \
	pgsql_LIBS="-L/opt/pgsql/lib -lpq"
