Re: Cloning schemas

Adrian,

The code that CREATES the TABLE is

EXECUTE 'CREATE TABLE ' || buffer || ' (LIKE ' || quote_ident(source_schema) || '.' || quote_ident(object)
        || ' INCLUDING ALL)';

The schema names are supposed to be changed!

This function HAS been tested and does WORK. Please do not muddle the problem without testing yourself.

This is not related to the clone_schema function. It looks like you may have corruption in your syste catalogs,
Try reindexing your system_catalogs.

Or from clone_schema.sql:

EXECUTE 'CREATE TABLE ' || buffer || ' (LIKE ' || quote_ident(source_schema) || '.' || quote_ident(object)
        || ' INCLUDING ALL)';

https://www.postgresql.org/docs/10/static/sql-createtable.html

"LIKE source_table [ like_option ... ]

...

Indexes, PRIMARY KEY, UNIQUE, and EXCLUDE constraints on the original table will be created on the new table only if INCLUDING INDEXES is specified. <*/Names for the new indexes and constraints are chosen according to the default rules, regardless of how the originals were named. (This behavior avoids possible duplicate-name failures for the new indexes.)/*>

...
INCLUDING ALL is an abbreviated form of INCLUDING COMMENTS INCLUDING CONSTRAINTS INCLUDING DEFAULTS INCLUDING IDENTITY INCLUDING INDEXES INCLUDING STATISTICS INCLUDING STORAGE.

..."

See tagged part(<*/ /*>) part above. I could see where the indexes in the new schema have new names while the index comments in the old schema refer to the old name. Then you would get the error the OP showed.

REINDEX VERBOSE SYSTEM  <your_database_name>;
