Prepared statements maximum bindings

I am trying to do some big bulk inserts to Postgres via node-postgres When the bindings array exceeds 65536 values then passes to postgres the rest of values and when the query it runs I take the error

[error: bind message supplies 4 parameters, but prepared statement "" requires 65540]

@brianc It would still be useful if this would somehow throw a different error.

As it stands, for a parameterized query with X parameters you just get the error [bind message supplies X modulo 65536 parameters, but prepared statement “” requires X] which is very unhelpful for diagnosing the cause for the problem.

Also the limit of 34464 parameters is wrong, at least for postgresql 9.6.3 I can do a single insert with 65535 parameters without problems.

@konhondros Postgres itself doesn’t support more than 34464 parameters for a bound statement. You’ll need to break up your bulk insert into multiple statements.
