Обсуждение: restriction clause selectivity bad value

Can somebody translate this error to english for me :)

ERROR: RestrictionClauseSelectivity: bad value 2.451276

I'm getting it whenever I try to run an update query through ODBC.. any
ideas?

Thanks,

Ted Wallingford

I got an error like this after use alter table to add a column

when I do a select I got this:


database=> select * from table where column = 1;
ERROR:  RestrictionClauseSelectivity: bad value 2.452260

but if i do :
select * from table where column > 1;
it goes ok.

strange...

My guess is you are running Alpha and you did an ALTER TABLE ADD
COLUMN, and not running 6.5.*.

In any event, run VACUUM ANALYZE on the table and it will be fixed.

VACUUM ANALYZE the table.  6.5.* should not have this problem.
