problem migratin from ms sql

I wish to migrate from ms sql server to postgresql... an application (windows executable) not developed by me then no sources. We buyed for a lot of money so we must run it on windows clients.
All works greatly, and with more performance too, from php I can do few scripts without any problem.
But there is a problem: for some reports this application create a temporary table... with ms sql / sybase (t-sql) syntax !
create table #mytable( title_id char(6), total_money_made money ) insert into #mytable select title_id, total_money_made=sum( ytd_sales*price ) from titles group by title_id select * from #mytable drop table #mytable Of course odbc driver for postgresql reports a syntax error due to the table name !
There is a way to do this with postgres ?!?

Thank you in advance, best regards
