hi strk,

good to hear from you again :-) .

thanks for considering my input.

i wouldn't dare proposing you, since i'm not familiar with c datatypes
in postgresql.

using -lpq you don't make the linker autodetect it's libraries, but you
actually choose to link with this library (libpq.so), but not the other
libraries returned by pg_config --libs, but not actually used by
pgsql2shp, which is the only binary built with this functionality.

on the contrary, calling pg_config --libdir *is usefull*, since this
would be added to the libraries searchpath, for the specified libraries.

hope this helps,

alex
