I will raise your revenues or decrease your costs using solutions based on logic and in most cases, it will involve a computer. Design - Build - Improve.
I design solutions to your business problem, build it with you and your team and finally scale the solution to fix other related problems.
I use Javascript and Python as the main languages for development but I am eager and faster to learn anything that would be put a solution on the table.
Most likely it's because your system shutdown unexpectedly Try
postgres -D /opt/homebrew/var/postgres # for Intel M1
postgres -D /usr/local/var/postgres # for Silicon
You might see
FATAL: lock file "postmaster.pid" already exists
HINT: Is another postmaster (PID 449) running in data directory "/usr/local/var/postgres"?
Then try
kill -9 PID
example
kill -9 449 And it should start postgres normally
