Thanks for the link.
select * from pg_ts_cfg where oid=show_curcfg();
ts_name | prs_name | locale
---------+----------+-------------
simple | default | en_US.UTF-8
That's helped me understand that the default config used by the tsearch2() function is not 'default' but 'simple' but I still don't understand why 'simple' is not working when both default and simple have the same locale set in pg_ts_cfg (en_US.UTF-8). Am i missing something?
