Supports versions of PostgreSQL 8.4 - 9.6. Higher versions throw errors. Checked it with Windows Defender on 2019-02-07: No viruses! Therefore I'll give it four stars: Functionality as expected, but not an actual version. The moment it supports the actual versions I'll change the assessment to five stars. But that's quite improbable because the newer versions of PG Admin contain a lot of additional functionality that might not be easily implemented.
I tried to download the files PgAdminPortable_1.22.1.paf.exe and PgAdminPortable_1.22.2.paf.exe. They both are positive on virustotal.com. Be aware!
Great portable version of the PgAdmin application. I use it extensively to control my PostgreSQL Portable instance - and it works great!!
