Previously, when use_scram_passthrough was specified on both a foreign server and a user mapping, the server-level setting took precedence over the user-mapping setting. This was inconsistent with the usual semantics of postgres_fdw options, where foreign server options provide shared defaults and user mapping options override them on a per-user basis. This commit updates postgres_fdw so that the user-mapping setting takes precedence when use_scram_passthrough is specified in both places. This matches the behavior of other connection options such as sslcert and sslkey. Backpatch to v18, where use_scram_passthrough was introduced. In v18, this only affects limited configurations that specify conflicting values at both the foreign server and user-mapping levels. In such cases, users would naturally expect the user-mapping setting to override the server-level setting, so changing the behavior should be minimally disruptive. Also keeping v18 as the only branch with different semantics for use_scram_passthrough would be unnecessarily confusing, so backpatch this fix to v18.
