can't create tables with a $

[moma]

Hi,

i am using postgresql 7.4.7 on an ubuntu box, perl 5.8.4 and DBI version
1.46 with DBD::Pg version 1.32.
i can create tables from psql with an $ in the middle of it, e.g. "create
table foo$bar (id integer);"
But if i try to do this
$dbh->do("create table foo\$bar (id integer);");
in a script, then following error is emiited:
DBD::Pg::db do failed: Execute called with an unbound placeholder

So i want to know, is it a bug or intended for portability?

thanks
