Sorry for slightly off-topic, but is there some way in
JDBC to detect if the connection supports
pre-compilation of prepared statements.

No. as the backend doesn't currently supports it. As soon as it does, it
will do.

PreparedStatement is currently handled purely by the JDBC driver. As soon as
"pre-compilation" is supported, then the performance improvement would be
immense.

Isn't creating a function the same as precompiling?
