Updating an extension does not replace the previous version

[twister65]

Steps to reproduce the issue

Update any extension with a postgreSQL database installed.

For example :

• Install Sigplus 1.4.3.2 : https://bitbucket.org/hunyadi/sigplus/downloads/pkg_sigplus-1.4.3.2.zip
• Go to Extensions -> Manage -> Update
• Click on "Find Updates" button
• Select and Update Sigplus 1.4.3.3.

Expected result

The previous version of the extension is replaced by the new one.

Actual result

The previous version and the new version of the extension are still there.

System information (as much as possible)

Joomla v3.9 (or staging) with postgreSQL.

Additional comments

It works fine with a mySQL database.
