Hi Rajesh,
I don't know why but the example you gave me did not work. Here is what
happened when I tried:
==========
pubs_test=# UPDATE publications SET url = replace( 'www.srs.fs.fed.us' ,
'www.srs.fs.usda.gov' , url ) WHERE url ilike '%www.srs.fs.fed.us%';
ERROR: Function 'replace(unknown, unknown, text)' does not exist
Unable to identify a function that satisfies the given argument types
You may need to add explicit typecasts
==========
Obviously I am a newbie at PostgreSQL (I have also joined the Novice
mailing list to learn more) so I can not tell you why your example did not
work, perhaps someone else with more experience can add some information.
Best,
--rdm
