Hi, I am working on a redundant system (master/slave) with postgres (8.1.2) and slony (1.1.5). When I was trying to upgrade my application software on master DB, I got following error:
********************************************************************************************************* <stdin>:5: PGRES_FATAL_ERROR select "_mswcluster".uninstallNode(); - ERROR: relation 27668 deleted while sti ll in use CONTEXT: SQL statement "lock table "_mycluster".sl_config_lock" PL/pgSQL function "uninstallnode" line 7 at SQL statement <stdin>:7: Failed to uninstall node from cluster ********************************************************************************************************* I am not able to understand why it failed to uninstall the slave node. Just before unintalling the other node I had performed switch over. But I am not sure whether that triggered the problem but it is not reproducible. Is it race condition? This problem is of slony or postgres? Please ....any body can help me!! Thanks -Shalendra
