PG 9.4.x has been out of support since 2020 [1].  You need to be
looking to upgrade that server to something that's in support, and
then you can probably find a matching in-support oracle_fdw version.

 From what I see ChatGPT is making things up again.

If you go here:

https://github.com/laurenz/oracle_fdw

the tags go from:

https://github.com/laurenz/oracle_fdw/tree/ORACLE_FDW_1_5_0

to

https://github.com/laurenz/oracle_fdw/tree/ORACLE_FDW_2_0_0

Personally I would try the 2.0 version. That came out(2017-09-15) in the 
middle of 9.4's life span(9.4     9.4.26     No     December 18, 2014     February 
13, 2020).

The API between PostgreSQL and foreign data wrappers has changed significantly since 9.4.  As Tom mentioned, you need
toupgrade your server to something in-support.

your compatibility problem is not with Postgres 9.4.x at all, but with
some version of Greenplum.  (Aside from the giveaway include path, no
extant version of community Postgres has a cost.h file that is as much
as 225 lines long, nor do we expect clauselist_selectivity to take
more than five arguments.)  Please speak to Greenplum customer
support, rather than expecting the wider Postgres community to help
you for free with a code base that we don't even know.

FWIW oracle_fdw should actually build against PostgreSQL as far back as 9.3
(though finding packages would be a fruitless endeavour); the documentation
does explicitly mention that it will likely not build against forks which are
not compatible with the community code [1].

It seems more like you're not actually using PostgreSQL, but are instead
using a special proprietary spin-off called Greenplum.

If that's the case, then you'll need to have a chat with the Greenplum
support people.  They'll know their product better than we do. :)

Regards and best wishes,

In your first post you said:

"Can you provide us download links for oracle_fdw for psql (PostgreSQL) 
9.4.24. ..."

1) Are you on 9.2 or 9.4?

2) Where did you get Postgres from?
