Hi Everybody, I am experimenting with backups and restores.... I am running into something curious and would appreciate any suggestions.
Backing up from: Postgres 8.3.0 Windows 2003 sp1 server (32bit) - Took a compressed binary backup of a single db (the default option in pgAdminIII, right click backup) - Took a plane backup of the same single db, (plane option in the right click backup gui in pgAdminIII) Restoring to: Postgres 9.1.3 Windows 2008 R2 (64bit) Aside from not finding the pldbgapi.dll, when restoring, what seem to contain debug functions - Tried restoring the compressed binary backup with pg_restore - Error o I get an error message: pg_restore [archiver (db)] could not execute query: ERROR: permissions denied for schema bob § The bob schema is owned by the bob user, which is superuser, it is the user with which I am restoring § The object being restored : · will be placed in and owned by a user/schema rob, · the name for this object is derived from a query from a bob owned/stored table, · rob is not superuser · all schemas grant usage privs to public · all users are part of public - Tried restoring the plane backup as a .sql file in psql, as the bob user - Success ! o The object in question was created Question #1: what does the error mean? - Does it mean that the bob user cannot create an object in the rob schema? - Does it mean that the bob user cannot query from an object stored in the bob schema and owned by bob? Question #2: if the restore was successful from a sql file but not from a dump file, where is the difference in the restoration process from those two files? - Is there a difference in locking or concurrency mechanisms employed by those two restoration methods? - I listed out the objects in the dump file, does the list indicate the order of restoration? Question #3: the object is a gist index, we are also restoring a btree index, the btree index name also derives from a query on a bob owned/stored table, and yet the btree index gets created with both restoration methods, but the gist does not - Could this experience have anything to do with this being a gist index? Thank you, Sincerely, Kasia
