Neon CLI command: psql
Summary: Covers the usage of the
psqlcommand in the Neon CLI to open a psql session against a branch in your Neon project, including pooled connections and time-travel support.
Neon CLI command: psql
Section titled “Neon CLI command: psql”Connect to a Neon database via psql
The psql command connects to a database in your Neon project using the psql client. It builds a connection string for the specified branch (or the default branch from your context file) and launches psql, equivalent to running neon connection-string --psql as a dedicated top-level command.
If --project-id is omitted, the CLI resolves it from your context file, auto-selects when your account has only one project, and otherwise asks you to pass --project-id. --role-name and --database-name are needed only when the branch has more than one role or database.
neon psql [branch] [options] [-- psql-args]The [branch] is the branch name or ID. If omitted, the default branch from your context (or the project's default branch) is used. You can also use the point-in-time format branch@timestamp or branch@lsn for time travel connections. Arguments after -- are forwarded to psql.

neon psql uses the native psql binary from your $PATH if one is available, and otherwise falls back to a built-in TypeScript implementation, so no PostgreSQL client tools installation is required. The built-in implementation is a full port, not a simplified subset: it supports SCRAM-SHA-256 authentication, backslash commands (\d, \dt, \d+, etc.), tab completion, command history, and COPY. It's verified against Postgres 14 through 18.
To force the built-in implementation in CI or other environments where native psql is present but you want consistent behavior, set NEONCTL_PSQL_FALLBACK=1.
Examples
Section titled “Examples”Connect to the default branch:
neon psqlConnect to a named branch. Projects created with the CLI or API get a default branch named main; Console-created projects use production (run neon branches list if you're unsure):
neon psql mainRun a single query:
neon psql main -- -c "SELECT version()"Run an SQL file:
neon psql main -- -f dump.sqlConnect to a branch at a specific point in time:
neon psql main@2024-01-01T00:00:00ZUse a pooled connection:
neon psql --pooledRelated docs (Connect to Postgres)
