new version 1.4.9 fails installation on Alpine Linux

ERROR: compilation failed for package 'RPostgres'

To reproduce the error in a standard docker run --rm -it alpine, you could do:

apk add R R-dev R-doc
apk add g++ libpq-dev
R -s -e 'install.packages("RPostgres", repos = "https://cloud.r-project.org/", Ncpus = 4)'

I get the same error as bastistician using the rhub/r-minimal docker image. Even going back to the minimal version of https://github.com/r-hub/r-minimal/blob/main/examples/RPostgres/Dockerfile the error persists

Thanks for raising and confirming, I'm investigating.

Fixed on Alpine in 12053be (most recent main), can you please confirm?

[bastistician]

can you please confirm?

Most easily with (the URL to) an updated package tarball. (Some more involved packages do a lot of bootstrapping to build that.) But I can say that remotes::install_github("r-dbi/RPostgres") as suggested in the README works for me.

Thanks for the quick fix! It would be good to get the patch released on CRAN as well.
