Hello, I would like to request a clarification in the pg_dumpall documentation regarding Large Objects (LOBs). The current documentation does not explicitly state whether pg_dumpall includes Large Objects in its output.
In the source code (pg_dumpall.c), there is a comment indicating that pg_dumpall forces all pg_dump output to plain text. Since Large Objects are only included by pg_dump when using -b or non-text archive formats (custom/tar), pg_dumpall cannot include LOBs in its output. This behavior is clear from the implementation, but not from the documentation. I propose adding an explicit note such as: "pg_dumpall does not include Large Objects (BLOBs). To back up Large Objects, use pg_dump -b per database." This clarification would help prevent user confusion during cluster-wide backup procedures. Thank you. Best regards, Dimitre Radoulov
