Can't connect to PostgreSQL in Rstudio, possible permissions issue? - r

Question

I've followed the documentation on db.rstudio.com and other sites, and I'm not able to connect to my Postgres database from Rstudio. I'm on macos 10.14. Running:
con <- DBI::dbConnect(odbc::odbc(),
Driver = "PostgreSQL Driver",
Database = "mydatabase",
UID = "myuser",
PWD = "mypassword",
Host = "localhost",
Port = 5432)
Gives the error:
Error: nanodbc/nanodbc.cpp:983: 00000:
At first, I got an empty list when running odbcListDrivers(), however I was able to get it to show the postgres driver location/value by copying odbcinst.ini from the global /etc to my user (cp /etc/odbcinst.ini ~/.odbcinst.ini).
Similarly, odbcListDataSources() returned nothing until I did the same thing (cp /etc/odbc.ini ~/.odbc.ini)
The odbc.ini and odbcinst.ini are locked from editing via Finder, but can be edited via nano/terminal.
I also tried to solve the problem by installing the database drivers via Postgres' stack builder, but it didn't change anything.
Overall I'm suspecting that it's a permissions issue, but I'm not quite sure where to look next.
Thanks for your help!
The permission for the odbc.ini was:
-rw-rw-rw-# 1 root wheel 139B Mar 31 12:57 odbc.ini
Which I changed to:
-rwxr-xr-x# 1 myuser wheel 139B Mar 31 12:57 odbc.ini
But that didn't solve the problem, the error is the same.
The content of odbcinst.ini is:
[PostgreSQL Driver]
Driver = /usr/local/lib/psqlodbcw.so
The content of odbc.ini is:
[PostgreSQL]
Driver = PostgreSQL Driver
Database = mydatabase
Servername = localhost
UserName = myuser
Password = mypassword
Port = 5432
odbc::odbcListDrivers() gives:
name attribute
1 PostgreSQL Driver Driver
2 ODBC Drivers Amazon Redshift
3 Amazon Redshift Driver
value
1 /usr/local/lib/psqlodbcw.so
2 Installed

odbc::odbcListDataSources() gives:
