one command in SQL?
I need to remove all vowels (a,e,i,o,u) in a field. How would
I go about that?
Try something like
SELECT regexp_replace(your_string,'[aeiou]','','g') ...

There's a limit of (I think) 2-4 billion commands per transaction. Each

Hi all,
I wonder why this happens:
- postgres: 8.1.3
- the table has ~200 million rows;
- there is a primary key on (col_1, col_2);
- the table was ANALYZEd;
- the planner chooses seqscan+sort for the following query even with
enable_seqscan=off:
select * from table order by col_1;
Isn't
Csaba Nagy wrote:
select * from table order by col_1;
Isn't it supposed to choose the index scan at least when
enable_seqscan=off ? Even if it is indeed not faster to do the index
scan than seqscan+sort.
I think because you've asked for every row, it's going to have to scan
the whole table

Without a WHERE you get the whole table.
A Index-Scan is, in this case, expensive.

I know that, and I would agree if I wouldn't have asked for _ordered_
result, and wouldn't have turned enable_seqscan=off.
In these conditions I would have expected an index scan, even if it is
more expensive
hm. Ok.
The log file contains a PID field, IIRC. Does that PID:
1) Stay the same, or change?
2) Match postmaster, or postgres.exe? If postgres.exe, is it just a
backend?
3) If it's just a backend, is it enough to kill off that backend?
