Re: Issues with building snap packages and psql

Hello,

After some further investigation and collaboration with #postgresql it 
looks like what we have here is an actual bug or at least improper 
implementation. Apparently, we use getpwuid on the euid to locate the 
'home directory'. This is incorrect (as well as inconsistent to our own 
documentation) [1]. Our documentation says that dotfiles are 
~/.whatever, and ~ on its own in shell means the value of $HOME, it does 
NOT mean the current user's homedir from getpwuid.


It is also inconsistent with how other programs behave. For example if 
psql uses readline, and you change the value of $HOME, then readline 
uses $HOME/.inputrc whereas psql does not use $HOME/.psqlrc.

Sincerely,

JD
