Hi,
After a little test i manneged to create a shared library for
postmaster.
Originally the postmaster program was 3922308 bytes large, but after a
small modification in src/backend/Makefile it have a postgres binary of
26812 bytes and one shared library of 3981064 bytes.
This should save 115 megabytes of memory when 32 postmaster processed
have started!!
Could anyone find a reason not to do it this way?
BTW. The modification is:
postgres: fmgr.h $(OBJS) $(VERSIONOBJ)
$(CC) -all -shared $(LDFLAGS) -o libpgback.so $(OBJS) $(OBJS1)
$(VERSIONOBJ)
$(CC) $(CFLAGS) -o postgres main/SUBSYS.o -L. $(LDFLAGS)
-lpgback
instead of:
postgres: fmgr.h $(OBJS) $(VERSIONOBJ)
$(CC) $(CFLAGS) -o postgres $(OBJS) $(OBJS1) $(VERSIONOBJ)
$(LDFLAGS)
