Hmmm, what I proposed earlier (CREATE INDEX foo ON employees (UPPER(firstname));) seems to work fine in 7.1 but not 7.0.2.
Cheers...

Subject: [GENERAL] Regular expression question
Does the regular expression parser have anything equivalent to Perl's \w
word boundary metacharacter?
I want to select tuples where a text field contains a certail whole word.
Using fieldname ~* 'searchword' wont work because it picks up the
searchword emdedded in other words. Using ~*' searchword ' wont find it at
the beginning or end of the string.
So far we have:
field ~*' searchword ' OR field ~*'^searchword ' OR field ~*' searchword$'
but I would like something more elegant.
