Executing the ght-restore-pg on the data from 2018-09-01 gives the following error:
ERROR: value too long for type character varying(356)
CONTEXT: COPY commit_comments, line 2315625, column body: "@@ -0,0 +1,462 @@
this is due to the fact that the field body in commit_comments is specified as varying(356) in pg_schema.sql. I suggest changing the type to text.
To my knowledge this doesn't have any negative effect on space requirements and should even increase import performance since length of the data doesn't need to be checked. Should I submit a PR?
