The current approach depends on syscache callbacks anyway. Backend 2 (from the example above) knows is it necessary to unpin segments after syscache callback was called. Tom pointed below that callbacks are occured in various events. So I think I should check the current approach too using CLOBBER_CACHE_ALWAYS. It could show some problems in the current patch. Then if everything is OK I think I'll check another approach (unmapping in TS syscache callback) using CLOBBER_CACHE_ALWAYS. -- Arthur Zakirov Postgres Professional: http://www.postgrespro.com Russian Postgres Company
