    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?
