Postgresql：psql：未找到命令

Question

我安装了Postgresql

sudo apt install postgresql

但psql失踪

$ type psql
type: Could not find "psql"
$ find / -name psql 2>/dev/null
/snap/core/6818/usr/share/bash-completion/completions/psql
/snap/core/6673/usr/share/bash-completion/completions/psql
$

如果缺少命令行客户端，如何使用 Postgres？
