Description:

Hello!
I have a "allow/deny" dialog box that comes up constantly on my mac for
about 1 second and then goes away.
The dialog message box reads : "do you want the application "postgres" to
accept incoming network connections"
This message comes up and down so quickly I had to record the screen with my
cellphone to be able to read the dialogue box

This happens hundreds of times per day. The dialog stops any and all video
playback, editing, whatever.
Since my job is Video editor, VJ, Projection specialist - this issue
effectively has ruined my computer for actual work.

At the suggestion of several online posts about this exact issue:
I have checked Settings > Users/Groups > Login Items Postgres is not
there.
I have gone into Settings > Security & Privacy > Firewall > delete postgres
( - button)
I have deleted Davinci Resolve (mentioned in conjunction with this problem
*a lot* )

What can I do? How can I make this stop?
Will even try voodoo chants, spells and various incantations. (no blood :
)

thanks much
JD
