I have a problem while loading the pg_tde.so shared lib.
contrib/pg_tde was built with:

but the shared lib /usr/local/sisis-pap/pgsql-16.2/lib/pg_tde.so
can't be loaded on startup of the server:

This is the OpenSSL version of SuSE Linux Enterprise 15 SP5:
# openssl version
OpenSSL 1.1.1l-fips 24 Aug 2021 SUSE release 150500.17.25.1
This is what we have compiled and PostgreSQL should use:
# export LD_LIBRARY_PATH=/usr/local/sisis-pap/lib
# /usr/local/sisis-pap/bin/openssl version
OpenSSL 1.1.1t 7 Feb 2023
I see three different versions of OpenSSL:
OPENSSL_1_1_1d -- From error messsage
OpenSSL 1.1.1l-fips -- SuSE 15 version
OpenSSL 1.1.1t -- Your built version?
Are you sure you pointing at the same version in all cases?
When I disable 'pg_tde' in data/postgresql.auto.conf the server
starts fine;
vim /data/postgresql162/data/postgresql.auto.conf
# disabled shared_preload_libraries = 'pg_tde'
# /etc/init.d/postgres162 start
starts fine
and the postgres proc is using our libssl.so.1.1
# lsof -p 17254 | egrep 'libssl'
postgres 17254 postgres mem REG 254,0 697248 1080241
/usr/local/sisis-pap/lib/libssl.so.1.1
# strings /usr/local/sisis-pap/lib/libssl.so.1.1 | grep EVP_KDF
(nix)
# strings /usr/lib64/libssh.so.4 | grep EVP_KDF
EVP_KDF_CTX_new_id
EVP_KDF_ctrl
EVP_KDF_CTX_free
EVP_KDF_derive
I have a complete different OpenSSL 3.0.x environment: all OpenSSL
consumers use /usr/local/sisis-pap.sp01/lib/libssl.so.3, also
PostgreSQL and pg_tde have been compiled against this; and this
runs fine with 'pg_tde'.
What the avove error means?
Thanks
