Re: bug regclass::oid

hi again

here is my query
*select A.table_name as "table_name",A.domain_name as "domain",*
* format_type(c.atttypid, c.atttypmod) AS data_type ,A.column_name as
"column_name",*
* A.is_nullable as "nullable",A.column_default as "default"*
* from information_schema.columns A inner join pg_attribute c
on a.table_name::regclass::oid=c.attrelid*
* where a.table_schema in (select current_schema()) and a.column_name
=c.attname ;*

if i run this query in any database contain at least one table with space
in their name , an error will occur
if i run this query in other database will work fine
I tested this on pg 11.1 , pg 10.3, pg 9.6
