Hi folks! I'm try to upgrade version from 9.3.5 to 9.6.1, but in the 9.3.5 I installed the sslutils to monitoring server with a agent, but now when I want upgrade show this error pg_upgrade: /Checking for presence of required libraries fatal Your installation references loadable libraries that are missing from the new installation. You can add these libraries to the new installation, or remove the functions using them from the old installation. A list of problem libraries is in the file: loadable_libraries.txt/ with a cat in loadable_libraries.txt show this: /could not load library "$libdir/sslutils": ERROR: could not access file "$libdir/sslutils": No such file or directory / I installed in the new version 9.6.1 the same sslutil's version and process that 9.3.5 and show this error: /Consult the last few lines of "pg_upgrade_dump_68706.log" for the probable cause of the failure.

Any Suggestions? Best Regards. DrakoRod ----- Dame un poco de fe, eso me bastará.
