Deleting comments

[iriswind]

The developers in my team noticed that the comments that they left on the indexes were deleted.
Apparently, it is not a reindex concurrently operation that is being produced, but the creation of a new index and the removal of the old one.
I give a diff that may close this problem:

801,802c801
<     pg_catalog.pg_relation_size(indexoid) as idxsize,
<     coalesce(obj_description(cst.oid),obj_description(indexoid)) as comm
---
>     pg_catalog.pg_relation_size(indexoid) as idxsize
819c818
< LEFT JOIN pg_catalog.pg_constraint cst ON
---
> LEFT JOIN pg_catalog.pg_constraint ON
902,903c901
< DROP INDEX CONCURRENTLY " . _dbh->quote_identifier($schema_name) . "." . _dbh->quote_identifier($tmp_index_name) . ";
< COMMENT ON INDEX " . _dbh->quote_identifier($schema_name) . "." . _dbh->quote_identifier($index_data->{indexname}) . " IS " . _dbh->quote($index_data->{comm}) ;
---
> DROP INDEX CONCURRENTLY " . _dbh->quote_identifier($schema_name) . "." . _dbh->quote_identifier($tmp_index_name) . ";";

Yeah, I remembered this when I helped implement native reindex concurrently in postgresql 12.
Not sure if it makes sense now. The tool uses native reindex concurrently if available. Old-style create-rename-drop is a bit deprecated.
