With MSVC, you have to link with the mylibrary.lib file if you want to use
functions from the shared library mylibrary.dll.
This is not necessary on Linux, where references to a shared library are resolved
at load time.
So the answer to the original question is that there is no replacement
for postgres.lib on Linux because you don't need it to link with PostgreSQL.
It is enough to #include the required PostgreSQL headers during compilation.
Some information on how to link on Linux can be found here:

But as others have remarked, using PGXS is much better than doing
it by hand.
