Thank you Adrian for the response,

 

We are looking for 32bit client drivers for RHEL 8.5.

The ODBC driver does it:

https://odbc.postgresql.org/docs/win32-compilation.html 

Also the Build farm:

https://buildfarm.postgresql.org/cgi-bin/show_status.pl 

has 32bit/i686 members that show green.

Try it and see.
