The report only showed that that one was the first the linker found.
The 7.4 libpq does include path.c in its entirety, meaning that there
are potentially dependencies out there for all of the symbols defined by
7.4 path.c: is_absolute_path, first_path_separator, last_path_separator,
in addition to get_progname. In the 8.0 version of path.c these symbols
are intertwined with a bunch more; what's more, is_absolute_path is now
a macro not a routine, so we lost ABI compatibility anyway. (I do in
fact see is_absolute_path used in 7.4 psql; didn't bother looking for
the others.)
In short, fixing this the way Bruce wants to will be a nontrivial amount
of effort.
