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

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?

Not always. PreparedStatements can be created on the fly from any
select/update/insert query and as such can return rows (something that
functions can't). They also only live the length of the query.
