Add FDW/DBLink password obfuscation feature to comparison table in advanced_security.mdx - #7217
Merged
Conversation
A customer (support ticket https://techsupport.enterprisedb.com/tickets/65024) asked to have `FDW/DBLink password obfuscation` added to the matrix. The change I made is valid: neither community PostgreSQL nor EDB Postgres Extended Server has a native way to obfuscate the password stored in pg_user_mapping. PG18's use_scram_passthrough (postgres_fdw only) avoids storing a password at all, but only when the local and remote SCRAM verifiers match -- it's a narrow workaround, not equivalent obfuscation.
