If I try to run "php maintenance/update.php" on a wiki that uses PostgreSQL as the database while UploadWizard is installed, it fails because extensions/UploadWizard/UploadWizard.sql tries to create a table uw_campaigns using syntax that is not valid in PostgreSQL.
If I inactivate the extension by commenting out the:
require_once( "$IP/extensions/UploadWizard/UploadWizard.php" );
then the upgrade completes. This leaves the uw_compaigns table missing.
Are there other extensions with db-engine-specific behavior, to serve as an example of the right way to fix this?
Presumably this problem applies to other branches as well, I only tested on 1.22.5 so far.
