# Downloads the official HP Printer Driver installer and patches its OS version gate,
# so it installs on macOS releases newer than Sequoia (15.x), e.g. Tahoe (26.x).
#
# Instructions:
# 1. save the whole contents as a new file, e.g. patch-hp-printer-driver.sh
# 2. make it executable. From a terminal, in the same folder where you saved it: chmod +x patch-hp-printer-driver.sh
# 3. run it: ./patch-hp-printer-driver.sh
# 4. The script will notify about the the patched installer (saved in the same folder). You can then run it to install the drivers.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
