Hi,


My name is Aravind and I am part of IBM CICS TX product development and 
support. We have a requirement from one of our customers to use IBM CICS TX 
with PostgreSQL 13/14. IBM CICS TX is a Transaction Manager middleware product 
that is deployed as container on Kubernetes platforms. IBM CICS TX can interact 
with database products such as DB2, Oracle, MSSQL, PostgreSQL through XA/Open 
standards.

CICS TX is a 32bit C runtime product and uses the databases’ 32bit client 
libraries to perform embedded SQL operations. The customer applications are 
Embedded SQL C or COBOL programs deployed on CICS TX and CICS TX runtime 
executes them as transactions ensuring the data integrity.

We observed there are no 32bit client binaries/libraries available with 
PostgreSQL 13/14 and CICS TX require them to interact with the PostgreSQL 
server. Currently we have tested with PostgreSQL 10.12.1 and our customer wants 
to upgrade to PostgreSQL 13 or 14.

Based on the above requirements and details, we have few questions which 
require your support.



  1.  Can we get 32bit client binaries/libraries for PostgreSQL 14 ?
  2.  We also found that the libraries can be built by using the PostgreSQL 14 
source. Is it possible to build the 32bit client binaries/libraries from the 
source available ?
  3.  Is there an official support for 32bit client libraries/binaries built 
out of source for customers ?
  4.  Can the PostgreSQL 10.12.1 client work with PostgreSQL 14 server ? Do you 
still support PostgreSQL 10.12.1 client ?


Thanks & Regards,
