Maybe you can extract stuff like IP addresses and words like 'error'
and put it in a separate column in the table. Full text search is not
a solution for data that is in a wrong format.

Hi,
Yes, you're right! I found out a functional index using this function and
ANALYZE also cancels.
Is there a way to code this function in a way VACUUM/ANALYZE does not
cancel?
Thank you!

Is there a way to regexp match on a null value? Or is it necessary to OR in a
"or x is null"?
Thanks in Advance !
Hey Dave,
Did you consider to use coalesce() ?

you could use a
COALESCE( text_column, '') ~ E'MyRegEx';
Or perhaps:
( text_column ~ E'MyRegEx' ) IS UNKNOWN

Ya, I kinda knew about these approaches. The problem ahs to do with novice
users who don't know about coalesce or or;ing a check ofr nulls. I was hoping
there was some special regexp expression that would match to a null.
Thanks for the quick response, and have a great weekend !

As someone famous once said:
The documentation I've found on \copy says to see the docs on copy ;)
It's *supposed* to match the backend syntax, but seems a few bricks
shy of a load at the moment. Anyone feel like fixing it? See
parse_slash_copy() in src/bin/psql/copy.c.

Don't stay stuck there too long. It's about to end its life, as are
8.0 and 8.1, later this year.

What would be the regexp_split_to_table pattern that splits a comma
separated string into a table? Im having trouble when a string
contains commas or there are commas at the beginning or end
String
',one,two,''three,four'',five,six,'
Should return
,one
two
three,four
five
