In PostgreSQL, when a table data is viewed, I get the error "Data in this table cannot be edited because it has no primary key."
This is because the names are not properly escaped. To illustrate the problem, use the attached DB dump to create a database. Then edit each of the two tables in it and see the difference in behaviour even though both of the tables are the same apart from one table having names in all lowercase and the other in mixed case.
Thanks for reporting this - we'll fix this in the next release of Webmin.
Boy, that was fast. Thanks, Cameron. Looking forward to the update. If this fix works, then 5366 can also be closed. I guess they should be marked duplicates at the same time.
