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.
