Hello, I am not really sure if I am in the right mailing list, but I try it here first.
I have written a postgres C extension as DLL which was used with Postgres 9.2 successfully. Now I am trying to upgrade to Postgres 13 but I ran into a compile problem. The function PG_GETARG_BYTEA_P causes the compile error error LNK2019: unresolved external symbol _pg_detoast_datum referenced in function _compressBytea The Compiler is Microsoft Visual Studio 2010 Windows 10 Any idea what to do? Is PG_GETARG_BYTEA_P obsolete? Best regards, Eric
