CREATE INDEX idx_d_trh_code_id_partial
ON xmms.d_trh_table
USING btree
(code_id) where code_id not in ('P000','000') and code_id is not null;
ERROR: functions in index predicate must be marked IMMUTABLE
Just trying something new.
I want to create partial indexes on code_id which are not null and not
P000/000
the ones I want are like HMD11 or UE935 or OIOR11 etc.
not sure where the IMMUTABLE part is coming from..
Clue?
