Postgres View DDL

Howdy,

I have an Oracle view that's been converted for Postgres.  This block of
code in the Oracle view DDL:

TO_NUMBER (NVL (REGEXP_REPLACE (broker_mc, '[^0-9]+', ''), 0)),
TO_NUMBER (NVL (REGEXP_REPLACE (carrier_mc, '[^0-9]+', ''), 0)),
TO_NUMBER (NVL (REGEXP_REPLACE (freight_forwarder_mc, '[^0-9]+', ''), 0)),

has been converted for Postgres as:

(coalesce(REGEXP_REPLACE(broker_mc, '[^0-9]+', '', 'g'), 0))::numeric ,
(coalesce(REGEXP_REPLACE(carrier_mc, '[^0-9]+', '', 'g'), 0))::numeric ,
(coalesce(REGEXP_REPLACE(freight_forwarder_mc, '[^0-9]+', '', 'g'),
0))::numeric ,

which is throwing the following error:

ERROR:  COALESCE types text and integer cannot be matched
LINE 43: ...ce(REGEXP_REPLACE(broker_mc, '[^0-9]+', '', 'g'), 0))::numer...

                         ^
I have been looking through:

https://www.postgresql.org/docs/current/functions-conditional.html#FUNCTIONS-COALESCE-NVL-IFNULL
https://www.postgresql.org/docs/current/typeconv-union-case.html

but I'm not seeing a way to resolve it.  Would anyone be able to advise how
to correct this for Postgres, please?

Thanks,

Sam
