The 'real' problem was the database had not been re-indexed in a long
while (it is a test system). After re-indexing the db, the query below
ran fairly quicky:
>>> metadata=# SELECT * FROM viewspace.siap AS t WHERE
>>> t."startDate"='2008-10-27%' AND t.prop_id LIKE '%' LIMIT 1000;
The 'startDate' is a timestamp. I was just questioning the use of the
'=' operator with '%' instead of LIKE. I would have expected the '=' to
take the '%' as a literal.
Thanks Tom, Klint and Scott. I learned some debugging tips from this post.
