Argh.  Perhaps the problem is that it's somewhat 'overloaded'.  PG
supports *both* SQL-level PREPARE/EXECUTE commands and the more
traditional (well, in my view anyway...) API/protocol of PQprepare() and
PQexecPrepared().  When using the API/protocol, you don't actually
explicitly call the SQL 'PREPARE blah AS INSERT INTO', you just call
PQprepare() with 'INSERT INTO blah VALUES ($1, $2, $3);' and then call
PQexecPrepared() later.

That's the reason it's not documented in the SQL-level PREPARE docs,
anyway.  I'm not against adding some kind of reference there, but it's
not quite the way you think it is..
