Description:

Hello!

Try
pg_dump --format=p --schema=information_schema --schema-only --file=is.sql

It seams there are trailing spaces in the comment line
-- Name: sql_implementation_info; Type: TABLE; Schema: information_schema;
Owner: postgres; Tablespace:

Skip the string '; Tablespace: ' please, if there is no tablespace or put
'-' for the tablespace name in the same way as dash is used for Owner when
the option --no-owner is used.

Regards
Hans
