What is the query?
What is the schema for the tables in the query?
What is the cardinality of the tables?
What does the planner say, when you do this:
explain <query>
explain analyze <query>

Subject: [GENERAL] psql performance
How come when I paste a large query into psql it starts off fast but
then slows to a crawl eating up cpu just echoing the query back to me?
I'm using psql 7.4.7
