(609398 rows)

pma=> select count(*) from stck_dta_tbl_oprtnl;
 count
------
609398

When I do a select * from stck_dta_tbl_oprtnl; I get the whole table
just fine; but when I try and retrieve just 1 record which is out
put when doing the select * ie:

pma=> select * from stck_dta_tbl_oprtnl where stck_sym = 'ZRAN';
stck_sym|dta_date|dta_date_num|dta_date_dys|opn|hi|lw|cls|vol|unk
--------+--------+------------+------------+---+--+--+---+---+---
(0 rows)

I get 0 rows, and no errors from postmaster.

Is there a limit to the number of rows in a table?
I have also tried building a unique index composed of the stck_sym and
dta_date but I still get 0 rows.

I have also noticed that when setting up a cursor that the first fetch
does NOT get the first record in the table, it also returns nothing with
no errors from the postmaster.  I am wondering if these bugs are related.

Thanks all for your help!!!!
