+# SQL dump updates #
+
+## Dump ##
+
+This directory contains scripts to update database dumps to newer versions of the MariaDB server.
+
+## Background ##
+
+In some cases, restoring the database content from existing SQL dumps may not be possible in a
+straightforward manner. For those cases, this directory contains scripts to help with known issues.
+
+Examples for problems include:
+
+- New reserved keywords in MariaDB, that were previously used as identifiers in code.
+
+# Known issues and their fix #
+
+- SQL syntax error near `Offset INT UNSIGNED`: If a dump was made before MariaDB 10.6 (LinkAhead <
+ 0.15) and with the SQL backend before 7.0.3, there was a pramater named `Offset`. With MariaDB
+ 10.6 however, `OFFSET` became a reserved keyword. This can be fixed by running
+ `2024-10-02.dump_fix_mariadb_10_6.sh < yourdump.sql > yourdump.fixed.sql`
