I was thinking of the original purpose of preload_libraries, which was strictly performance optimization. But in the new world of plugins there may be functional reasons for wanting libraries to be loaded into backends --- and shared_preload_libraries is not isomorphic to local_preload_libraries. The permissions situation is different. Korry's right, we should force re-loading of shared_preload_libraries in the EXEC_BACKEND case. The needed documentation change is to point out that on Windows this is not a performance win, but it might still be wanted for instrumentation or debugging plugins. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
