Thread: Help! "alter table add column" hangs
Sorry, I had meant to write: The command ALTER TABLE some_table ADD COLUMN some_column CHAR(6) UNIQUE; ^^^^^^^^^^ hangs indefinitely (hours!), even though the table is relatively small (about 2500 records). What gives? Thanks, kj

This likely means that some other transaction has a lock on some_table. What does select * from pg_locks where relation=(select oid from pg_class where relname='some_table') show?
