Supported built-in functions

• abs(float) - Returns the absolute value of a given float. Example: abs(1) returns 1, and abs(-1) would also return 1, whereas abs(-3.14) would return 3.14. See also the signum function.

• basename(path) - Returns the last element of a path.

• base64decode(string) - Given a base64-encoded string, decodes it and returns the original string.

2021 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

docker run -it --rm --privileged --pid=host justincormack/nsenter1

First, check your current config (example output in homebrew.mxcl.postgresql.plist.xml lower down in this gist):

cat ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

Most importantly, note the -D /usr/local/var/postgres argument.

Second, shut down your current PostgreSQL.

launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
