Thanks for your reply,


Is it in executing the query (what does
EXPLAIN ANALYSE show)?

Here is the output of explain analyze SELECT * FROM "FILE"

"Seq Scan on "FILE" (cost=0.00..1.36 rows=36 width=235) (actual time=0.023..0.107 rows=36 loops=1)"

If you look at the "actual time" it's completing very quickly indeed. So - it must be something to do with either:
1. Fetching/formatting the data
2. Transferring the data to the client.

What happens if you only select half the rows? Does the time to run the select halve?
