Hello,
Is there a way for a streaming replication standby (client) to restrict its
list of supported TLS ciphers, similar to how the ssl_ciphers parameter
works on the primary server?
We need this for security compliance but can't find an equivalent setting
for the client-side connection in primary_conninfo.
Thanks,
