I have a table with about 16,000,000 rows in it.
When I do a:
SELECT * FROM <table> LIMIT 1;
it takes about 10 minutes (thats about how long it takes to do a full sequential scan).
I had originally thought that there might be a large number of "wasted/retired" tuples in the table so I "vacuum analysed" the database. It had no effect. I had a "vacuum full" going on the table for 17 hours before I killed it.
Any idea why its so slow? It used to be instant.
