Tablesample Function on Postgres 9.1 - Mailing list pgsql-sql

Hi,

I am trying to run a simple query to test out the tablesample function, but in postgres 9.1 it does not recognize the function. As from the wiki it seems like tablesample is supported (https://wiki.postgresql.org/wiki/TABLESAMPLE_Implementation)

The query I am trying to run is

select * from testtable TABLESAMPLE SYSTEM(10);

Is table sample not supported in Postgres9.1?

Thanks!
