Howdy:
Running PostgreSQL 7.2.1 on RedHat Linux 7.2.
I am not sure if I have asked this before, but,
how can I get the actual time in this statement:
[snip]
Nested Loop (cost=0.00..5662254656.82 rows=138 width=199)
[/snip]
The cost is supposed to be the amount of time it may take to
do a query, right? So what, exactly, is this? 500 hours?
minutes? CPU time?
How do I convert the cost time into regular human time? Putting
a date param before and after the statement won't really help me
in this situation as I need to figure out if I should even execute it
to begin with.
Thanks!
