Hi - been having a few problems like this myself. It's probably a
locale thing.
Here's at one of your problems:
-> Seq Scan on sms_new (cost=0.00..5240444.80
rows=138939341 width=8)
Filter: ((otid)::text !~~ 'ERROR%'::text)
I assume you have an index on sms_new?
Check the locale your database cluster has been set up with:
SHOW lc_ctype
if it doesn't come back with "C" as your locale, then you will have to
make sure your indexes are created as follows:
CREATE INDEX IDX_sms_new
ON YOUR_TABLE
USING btree
(sms_new varchar_pattern_ops);
Look at chapter 11.8 - Operator Classes for an explanation.
Unfortunately you'll need a second index if you want to use a non-
pattern matching operator, e.g. =.
If your locale is C, then I don't know what the problem is.
Hope that helps.
