Обсуждение: semicolons separating statements in a rule action body confuses parseQuery()

using jdbc-8.0-313 against 8.0.4,

the driver gets confused when parsing rule definition statements with
embedded semicolons such as :

"create rule r1 as on insert to foo do (delete from bar; insert into
bar select * from foo; );  "

the following patch shows a possible quick fix for
QueryExecutorImpl.parseQuery() in org/postgresql/core/v3/
QueryExecutorImpl.java

<             case ')':

Patch applied to 8.0 and head cvs branches.  For future reference we
prefer context diffs (diff -c) patches.
