Should I be using a different version? I am getting this error in RiverGIS:
"Couldn't connect to river database: bv mp3.5@localhost
Please, check you database connection settings!"
I have a friend who uses pgAdmin4 regularly for work and he said that I have that part setup correctly.
QGIS says that it is reading the database successfully. I tested this using > Data Source Manager > PostgreSQL >Create a New PostGIS Connection> Test Connection
