Ohh Thanks to all for your answers,
pgmemcache does exactly what I need, or how I need it, that is to
put my graph into a persistent memory for all transactions that have
permissions.
Thanks again,
Christian Gonzalez

Well, the PL/Perl and PL/Python languages do some variants of this using
their GD and SD variables. So it's surely possible in C as well.
Memory contexts are the right keyword, but note that if you use
TopMemoryContext, you are pretty much just using malloc(). Maybe you
want to try prototyping your functionality in PL/Perl or PL/Python to
get it started.
But if you want something visible to all sessions, something like
pg_memcache might be what you need. see
<http://cvs.pgfoundry.org/cgi-bin/cvsweb.cgi/~checkout~/pgmemcache/pgmemcache/README.pgmemcache?rev=1.11>
for some details.
cheers
