executing a dml within a utility - Mailing list pgsql-hackers

I created a CMD_UTILITY, which upon being executed by the user should do the 
following atomically:
1- drops a table
2- deletes from another table all rows with a certain criterion: "DELETE 
FROM pg_t1 WHERE att = val"
3- deletes from a third table all rows with a certain criterion: "DELETE 
FROM pg_t2 WHERE att = val"

I do the first step using ProcessUtility(). How can i do the 2nd/3rd steps? 
Any suggestions?

I tried calling exec_simple_query() but this didn't work. I am getting an 
error "cannot drop active portal"


Thanks a lot,
ehab
