When querying pg_description for the oid of one schema that has duplicates in pgAdmin I get this:
bix_live=# select * from pg_description where objoid = 16458;
objoid | classoid | objsubid | description
--------+----------+----------+--------------------------------------------------------------------------------------------------------
16458 | 2615 | 0 | The main comment
16458 | 1259 | 1 | some other comment
16458 | 1259 | 2 | yet another comment
16458 | 1259 | 3 | a different comment
16458 | 1259 | 4 | another different comment
(5 rows)
These are the comments that are displayed for the various duplicates in pgAdmin. Only the main comment is suppsed to be there, I don't know where the others come from. The extra comments are the same for all schemas that have duplicates.
