I'm running out of space on one of my partitions and I still have not
gotten all the data loaded yet. I've read that one could symlink the
pg_pg_xlog directory to another drive. I'm wondering if I can do the
same for specific tables as well.
Create another tablespace to the new location and the ALTER TABLE ... TABLESPACE newtablespace.
Thanks.
I've already done a pg_dump of the entire schema but have not dropped /
re-init the DB to another location cos I'm afraid I'll lose some items.
(I've to drop the DB, format the partition, merge it w/ another
partition and re-init the DB then restore the DB from the dump)
sigh.. wish it was easier, (meaning, like SQL Server where one can
detach an entire DB/tablespace and then re-attach it elsewhere)
If you are moving the whole cluster and can afford the downtime, you can shutdown the postmaster, move $PGDATA to a new location and then start postmaster from that new location.
