I'm having a problem with an index on a Postgres database.
I created an index as follows:
create index table1_column1 on table1 using hash (column1);
(column1 is a varchar(70))
I discovered that I couldn't actually use this index for anything; any
query which uses column1 in the where clause comes up with:
ERROR: hash table out of memory. Use -B parameter to increase buffers.
I then dropped it:
drop index table1_column1;
Now, I can't create an index with that name:
ERROR: cannot create table1_column1
In fact, the index doesn't seem to be *really* gone. Any query which
uses column1 still gives that error message. Whuzzup?
