I'm guessing this will work for < 12, as with 12 I'm now getting the following which looks like it's related to GSS encryption: "C:\Users\dpage\Downloads\postgresql-12.4\pgsql.sln" (default target) (1) -> "C:\Users\dpage\Downloads\postgresql-12.4\pgcrypto.vcxproj" (default target) (2) -> "C:\Users\dpage\Downloads\postgresql-12.4\postgres.vcxproj" (default target) (3) -> (Link target) -> be-secure-gssapi.obj : error LNK2019: unresolved external symbol setenv referenced in function secure_open_gssapi [C:\Users\dpage\Downloads\postgresql-12.4\postgres.vcxproj] .\Release\postgres\postgres.exe : fatal error LNK1120: 1 unresolved externals [C:\Users\dpage\Downloads\postgresql-12.4\postgres.vcxproj] I'll dig into that some more. -- Dave Page Blog: http://pgsnake.blogspot.com Twitter: @pgsnake EDB: http://www.enterprisedb.com
