Use PSQL and runWith on PostgreSQL

This page describes how to use Liquibase with the PSQL native executor on a PostgreSQL database.


  • Use Liquibase 4.13.0 or later.
  • Add PSQL to your PATH environment variable. Alternatively, pass its location in the liquibase.psql.conf file or from the command prompt during runtime. See liquibase.psql.path in the PSQL integration arguments section.

Note: Liquibase searches the executor location in the following order: runtime arguments, .conf file values, and then your PATH.


  1. Add the runWith attribute to the needed changesets in the changelog:
    • SQL: runWith:psql
    • XML: runWith="psql"
    • YAML: runWith: psql
    • JSON: "runWith": "psql"

    Tip: For more information, see the runWith and psql examples section.

  2. Specify the PSQL integration arguments in one of the following ways:
    • Pass the values at runtime on the command line
    • Add the values to liquibase.psql.conf or the Liquibase properties file.
    • Set the values as environment variables
    • Run the values as Java system properties (JAVA_OPTS) along with any command at the command prompt:
  3. Run a Liquibase command:
  4. Example: liquibase status --changelog-file=my_script.sql

    Note: If the command fails, you will receive an error message. However, if you add a property that is not used in Liquibase to the liquibase.psql.conf file, no error occurs. Liquibase only ignores it.

PSQL integration arguments

Note: Syntax for each parameter is specified in kebab-case (CLI and flow file), camelCase (properties file and JAVA_OPTS), and ENVAR_CASE (environment variable).

Syntax (--cli, propertiesFile, ENV_VAR) Type Description

Defines extra arguments to pass to the psql executable. For more information, see PSQL documentation.

Note: The delimiter for arguments is a space " ". Do not use a comma "," or semicolon ";".


Indicates whether or not to keep a temporary SQL file after the execution of PSQL. If true, the file is not deleted. Default: false.


Indicates the name of a temporary SQL file after the execution of PSQL. If no file name is specified, a name is automatically generated.


Specify the path in which to store the temporary files after the execution of PSQL. If not specified, the files will be stored in the system's temp directory.


Log file for PSQL output.


Path to psql executable.


Indicates seconds to wait for the psql timeout. -1 disables the timeout. 0 returns an error. Default: 1800 (30 minutes).

Best practices

  • Do not set the endDelimiter or splitStatements=true property on PSQL changesets. PSQL handles delimiters and statement splitting natively.
  • Prevent hanging queries by configuring the timeout. In your liquibase.psql.config file, add liquibase.psql.timeout=nn, where nn is time in seconds to wait before stopping the process.
  • Save the output of your spool files to your temp directory by adding liquibase.psql.keep.temp=true to the liquibase.psql.config file.
