Re: [HACKERS] Shared library conflicts
Thomas Hallgren [EMAIL PROTECTED] Another related question. What happens when I use --without-zlib? Does it have any effect on besides disabling compression for the dump/restore utilities? Is there anyway to make it affect the backend only? --without-zlib will affected LIBS and HAVE_LIBZ defined in configure. I searched HAVE_LIBZ in the source code, and find only pg_dump use it. I think we can change LIBS to not include -lz in configure, and add -lz for pg_dump in its Makefile.

Re: [HACKERS] Shared library conflicts
That's good news. Any chance of getting this fix backported to 8.1? Or at least, the libz part of it?
