Connection to AWS DB with RPostgres on M1 Mac #404
Comments
Thanks for the detailed report. A Redshift connection works with my M1 Mac, but I never tried Would you be comfortable cloning the repository and running a tweaked version for debugging? |
Sure, I'm happy to dig in. Thanks for the quick response. |
Thanks. Could you please try to find out which line of the dbConnect()
call fails?
|
It fails here with length(opts) > 0. |
Printing opts shows the correct dbname, user, host, and port. client_encoding is also set to "utf8". I tried setting it manually to utf16 and tried using check_interrupts as TRUE and FALSE but same error each time. |
I've further identified the issue happens in the DbConnection::DbConnection() function in the file DbConnection.cpp at |
Thanks. I wonder what RPostgreSQL is doing differently. Perhaps we can slightly change what we do here, to improve matters. |
I'm happy to try anything. I don't think anything's likely wrong with the package. I imagine I have some symlink issue or something preventing this from working correctly. |
If you could clone the RPostgreSQL code and take a look what the connection call is looking like there, and with what arguments? |
The connection call in RPostgreSQL is |
Thanks. When I run
Perhaps RPostgreSQL installation shows similar information? |
I installed RPostgreSQL from source and noticed this in the install logs. Above this, there were other checks that seem like they should have been successful, but weren't. For example, I can run pg_config on in terminal and get information, so checking for gcc... gcc |
Also when I run |
Good catch: 13.2 might come from our autobrew script. Can you try setting the |
Success! I had to set DISABLE_AUTOBREW to 1, and add /opt/homebrew/opt/libpq/bin to my PATH in RStudio, then install from source. Thanks so much for your patience with this! |
Thank you for pushing through! @jeroen: the autobrew version of libpq seems to be too old to support Redshift. What's the best way to proceed? |
I'll look into this. I upgraded the autobrew versions for MacOS 11.0+ (including arm) to libpq 14.5. So you can test those from: install.packages("RPostgres", repos = 'https://r-dbi.r-universe.dev') However CRAN still tarets macos high-sierra (10.13) and I'm having difficulty getting the new libpq to work on there. |
I've now also updated the other autobrew versions. So when you submit the next version to CRAN, new MacOS binaries will automatically be built with the new version. |
@samterfa: Is this still an issue with current CRAN binaries? |
I no longer use or have access to Redshift at work so I can't test this. You can close it. Thank you for your follow up! |

I have the exact same issue as this one that's been closed. I can connect to an AWS Redshift database just fine using RPostgreSQL but not RPostgres on my M1 MacBook Pro. I have copy and pasted the same code to a linux docker image running RStudio and I can connect just fine using RPostgres, but not on my M1 Mac using RPostgres. My colleague can connect using my exact same code on his Intel Mac. I can also connect using the RJDBC package. I can connect to the database using psql on the command line of my M1 Mac and run queries successfully so the connection between my laptop and the database seems solid. I have tried RPostgres::Redshift() but it didn't help. I simply receive this error immediately upon trying to connect.
Error: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.
The same error happens when running R at the command line too so it's not an RStudio issue I don't think but I do primarily work inside RStudio.
Changing the port or host to an invalid one, or turning off wifi makes it think and think and end up failing to connect. If port and host are correct and it's connected to wifi and I use an invalid user, password, or database name, it still gives the above error. So it definitely reaches out to the server but then doesn't actually try to authenticate.
Please include a minimal reproducible example (AKA a reprex). If you've never heard of a reprex before, start by reading https://www.tidyverse.org/help/#reprex.
RPostgres::dbConnect(RPostgres::Postgres(), host = host, port = port, user = user, password = password, dbname = dbname, sslmode = 'require')
. I've tried with and without specifying sslmode.This definitely seems operating system specific; I'm just hoping you can point me in the right direction. I tried the fix from the related issue but to no avail.
Thank you!
