Greets,
I've recently completed a lengthy repartitioning exercise on half a
dozen tables, restoring data, etc.
Something strange must have happened at some point (unrelated to the
partitioning exercise - a crash related to file descriptors if I
recall [not Pg's fault, mine]), because when I tried to modify a
parent table (which is partitioned):
ALTER TABLE tab ADD COLUMN col INT DEFAULT 0;
I get:
PANIC: right sibling's left-link doesn't match: block 35 links to 227
instead of expected 223 in index "pg_depend_depender_index"
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
-----
I also had some 'damage' in another partitioned table, which I
resolved with REINDEX TABLE on all the partitions (it failed on INSERT
with an error about block 0 read problem or something).
I then restarted Pg in single-user mode and reindexed all the system tables.
The aforementioned ALTER TABLE now completes without error. My
question is: can I trust the state/stability of the DB now, or should
I dump, re-initdb and restore from scratch? Only problem is the DB is
large and takes 24*n hours to restore, so this is a last resort.
Thanks
Henry
