I think the problem is you need to specify NEW.invoice in all comparisons
(don't quote the 'column')and always, Always, ALWAYS end each statement
with a semicolon.

IE:
IF (NEW.invoice <= 'I-10000') THEN INSERT INTO myschema.mywork VALUES (NEW.*)
ELSE IF (NEW.invoice >= 'I-10001' AND NEW.invoice <= 'I-20000')
    THEN INSERT INTO myschema.mywork VALUES (NEW.*);

Hi,

I am trying to setup partitions and as a test, I was able to follow the
example in the Postgres docs using the date as a condition.

Now I am trying to partition on a column with the data type character
varying. I want to partition based on an invoice ID consisting on letters
and numbers like I-10, I-11. I create my function:

IF ('invoice' <= 'I-10000') THEN INSERT INTO myschema.mywork VALUES (NEW.*)
ELSE IF ('invoice' >= 'I-10001' AND <= 'I-20000') THEN INSERT INTO
myschema.mywork VALUES (NEW.*)

ELSE RAISE EXCEPTION...

Is it possible to perform this type of operation with a mix of letters and
numbers? So far any attempts to insert based on these conditions raises the
exception.

Thanks.
