Hi,

does anyone have any pointers for shrinking tsvectors

I have looked at the contents of some of these fields and they contain many details that are not needed. For example...

"'+1':935,942 '-0500':72 '-0578':932 '-0667':938 '-266':937 '-873':944 '-9972':945 '/partners/application.html':222 '/partners/program/program-agreement.pdf':271 '/partners/reseller.html':181,1073 '01756':50,1083 '07767':54,1087 '1':753,771 '12':366 '14':66 (...)"
 

I am not interested in keeping the numbers or urls in the indexes.

select strip ('asd:23');
 strip
-------
 'asd'
(1 row)

 

Hi Oleg,

Is this function documented anywhere?
