A number of C functions were added in releases 4.2 to 4.4; however these were renamed in 5.3 to prevent naming clashes with other extensions. This does however mean that when upgrading from one of the above versions, the intermediate upgrade steps will attempt to create SQL functions referencing C functions which no longer exist in repmgr.so, and hence cause the upgrade to fail. We can work around this by providing empty upgrade scripts from these versions to 4.4, which skip the problematic CREATE FUNCTION commands. The functions will be correctly created in the 5.2--5.3 upgrade script.
