Hi,
Postgresql server 13.4 on RHEL8.4 FIPS, JAVA client use Postgres JDBC driver 42.3.3 to connect to database with TLS/SSL. Without fips mode, it’s ok to login with TLSv1.2 and default SSL parameters, but when enable fips mode on JAVA client side. It failed in below error:

does Postgres JDBC driver support JVM FIPS mode to connect to Postgresql database ? from postgresql jdbc driver not able to connect in FIPS mode - Red Hat Customer Portal , that show Postgresql jdbc driver does not support JVM in FIPS mode in RHEL8 .
Thanks,
