Embedded Postgres

Tests can’t start, with this error:

The initdb binary packaged with Embedded Postgres is of wrong arch:

While the one, installed with brew install postgresql apparently has the proper arch:

% file /opt/homebrew/bin/initdb
/opt/homebrew/bin/initdb: Mach-O 64-bit executable arm64

For now the issue is not solved. But there is a workaround. You need to override the path to Postgress installation when building the EmbeddedPostgress instance, like here:

val builder = EmbeddedPostgres.builder().setPgDirectoryResolver((_: Optional[File]) => new File("/opt/homebrew/Cellar/postgresql@12/12.9_1/"))
builder.start()
