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
