v_generate_tbl_ddl incorrectly pulls comments on tables with same name in different schema

v_generate_tbl_ddl pulls comments for tables with the same name in different schemas as the join to information_schema."columns" is only joining on table name. Correct this by adding a condition to join on schema as well as shown below:

OLD Line 273:
ON cl.ordinal_position::integer = des.objsubid AND cl.table_name::NAME = c.relname

NEW Line 273:
ON cl.ordinal_position::integer = des.objsubid AND cl.table_name::NAME = c.relname **AND cl.table_schema = n.nspname**

Search the repository for v_generate_tbl_ddl and inspect the join around line 273. Add the schema condition shown in the issue, then verify that comments are matched by both table name and schema for same-named tables.
