What kind of change does this PR introduce?
In cases where a column name is used included in multiple indexes on a table, the join between pg_attribute and pg_index will return a row for each index involving that column. Fix here is to select distinct columns in order to avoid duplicate column names on table creation in the sink.
What is the current behavior?
duplicate columns in sink table creation
What is the new behavior?
select unique column names
