Hello!
I've came across a weird bit in pg_upgrade/exec.c
We have a function check_bin_dir() which goes like this (old_cluster and
new_cluster are global variables):
void check_bin_dir(ClusterInfo *cluster)
{
...
get_bin_version(&old_cluster);
get_bin_version(&new_cluster);
...
}
This function has two calls:
check_bin_dir(&old_cluster);
check_bin_dir(&new_cluster);
I'd like to substitute these last two lines with this:
get_bin_version(cluster);
Doing it would simplify the patch I'm writing, but I'm worried I might
break something that's been there for a long time and has been working
fine. Is there maybe a reason for it to be this way that I don't happen
to understand?
Also, there's the exact same situation with the get_bin_version()
function in the same file.
