Subject: ODBC SSL connection issue on Solaris with PostgreSQL 18 (OpenSSL 1.0.2)
Date: Mon, 4 May 2026 19:16:28 +0530
Message-ID: <CABv4_i9=hL2rQY1-nt-6XqemdnTtp_jGO2mXKLR+aafvoNMDRA@mail.gmail.com> (raw)

Hi Team,

I am trying to configure PostgreSQL ODBC connectivity from an Oracle
Solaris server.
Since Solaris does not provide prebuilt PostgreSQL ODBC packages like
RHEL-based systems, the official PostgreSQL ODBC source code was downloaded
from the PostgreSQL repository and compile on the server.

Environment:
- OS: Solaris
- GCP CloudSQL PostgreSQL Server: Version 18
- ODBC Driver: psqlODBC 16
- PostgreSQL Client (libpq): 18
- OpenSSL: 1.0.2zj

Issue:
Connection fails with error:
"pg_hba.conf rejects connection ... no encryption"

Observation:
- PostgreSQL server enforces SSL (TLS 1.2+)
- Client build does not support SSL due to OpenSSL version
- PostgreSQL configure fails when enabling SSL:
  "OpenSSL version >= 1.1.1 is required"

Question:
Is there any supported way to enable SSL connectivity on Solaris with
OpenSSL 1.0.2, or is upgrading OpenSSL the only option?

Thanks,
Arun
