I'm trying to backup my postgreSQL 9.6 database using pgAdmin 4. First, when I tried to use backup, it failed saying that I have to set the binary path on my pgAdmin preferences. It maybe worth noting that I have recently changed the password of user postgres to postgres.
I googled this issue and found an answer (not sure if it's correct though), I set the value of PostgreSQL Binay Path to /usr/lib/postgresql.
However now when I try to back up a table, I get the following error:
I keep the defaults except for these values:
Only schema: YES
Use Column Insert: YES
Use Insert Commands: YES
Can anyone help me with this?
