For windows. Go to: https://www.postgresql.org/download/windows/ Find and click on :

“Advanced users can also download a zip archive of the binaries, without the installer.”

Unzip and go to location similar to: C:\Users\XXX\Downloads\postgresql-14.2-2-windows-x64-binaries\pgsql\bin. This will get you the latest version of postgres client and relevant utils (including pg_dump).

In separate window open: C:\Users\XXX\AppData\Roaming\DBeaverData\drivers\clients\postgresql\win In my case I had folder “13”. Create folder “14”. Copy contents from bin folder into this 14 folder.

in Dbeaver > Database > Driver manager > Postgres -> "Edit ..." -> Native client -> "Add Home" button -> Add newly created directory C:\Users\XXX\AppData\Roaming\DBeaverData\drivers\clients\postgresql\win\14

in Dbeaver > Find postgres connection -> Edit -> Local client -> change value to new directory

Enjoy. No more errors when backing up data… Similarly you could have multiple postgres clients installed and you could use each for different connections… But someone said they are backwards compatible so there is that.

p.s. I also updated driver version to latest maybe it’s also required… in Dbeaver > Database > Driver manager > Postgres -> "Edit ..." -> Libraries -> "Download/Update" button

Updated PG native client to version 12. It is backward compatible with 11 and 10 at least.
