If you want something that lasts for the lifetime of the backend, just do MemoryContext oldctx = MemoryContextSwitchTo(TopMemoryContext); ... MemoryContextSwitchTo(oldctx); I'm not sure what context you should expect in _PG_init(), although what you mention doesn't sound unreasonable. But generally if you want a long-lived context you should establish that explicitly yourself. We try to keep short-lived contexts active whenever possible because that avoids long-term leaks. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
