I see corresponding symptoms with the following Perl distributions: strawberry-perl-22.214.171.124-64bit.msi: src/pl/plperl/Util.c: loadable library and perl binaries are mismatched (got handshake key 0000000011800080, needed 0000000011c00080) ActivePerl-126.96.36.1992-MSWin32-x64-401627.exe: src/pl/plperl/Util.c: loadable library and perl binaries are mismatched (got handshake key 0000000011500080, needed 0000000011900080) So, this affects each of the two prominent families of Perl Windows binaries. Notes for anyone trying to reproduce: - Both of those Perl distributions require the hacks described here: https://www.postgresql.org/message-id/flat/CABcP5fjEjgOsh097cWnQrsK9yCswo4DZxp-V47DKCH-MxY9Gig%40mail.gmail.com - Add PERL_USE_UNSAFE_INC=1 to the environment until we update things to cope with this Perl 5.26 change: http://search.cpan.org/~xsawyerx/perl-5.26.0/pod/perldelta.pod#Removal_of_the_current_directory_(%22.%22)_from_@INC -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
