(If you're arguing against versions in shared libraries you're up against
much higher powers than PostgreSQL.)

I've found the problem.  Trond was right, it was the fact that the
programs are linked against libpq.so.2.1, not libpq.so.2.  And I was
right, too :-), in that it was the -soname switch, which essentially seems
to say "If you link with me, record that fact that I'm really <soname>."

If you want to fix this in the RPMs, do something along the following
lines (manually simulated patch) in Makefile.shlib:

 ifeq ($(PORTNAME), linux)
   install-shlib-dep     := install-shlib
   shlib                 := lib$(NAME)$(DLSUFFIX).$(SO_MAJOR_VERSION).$(SO_MINOR_VERSION)
-  LDFLAGS_SL            := -Bdynamic -shared -soname $(shlib)
+  LDFLAGS_SL            := -Bdynamic -shared -soname lib$(NAME)$(DLSUFFIX).$(SO_MAJOR_VERSION)
   LDFLAGS_ODBC          := -Bsymbolic -lc -lm
   SHLIB_LINK            += -lc
   CFLAGS                        += $(CFLAGS_SL)
 endif

Apps linked against the old libraries will not be fixed until relinked.
