Supported Versions and Support Levels

• For information regarding the supported version and support levels available, please see Supported Databases for Flyway
• For information regarding the Flyway features available, please see Flyway feature glossary

Driver

SQL Script Syntax

• Standard SQL syntax with statement delimiter ;
• Stored procedures (CREATE FUNCTION with $$ escapes, as generated by pg_dump)
• COPY ... FROM STDIN (as generated by pg_dump)

Compatibility

• DDL exported by pg_dump can be used unchanged in a Flyway migration.
• Any PostgreSQL sql script executed by Flyway, can be executed by the PostgreSQL command-line tool and other PostgreSQL-compatible tools (after the placeholders have been replaced).

Example

/* Single line comment */
CREATE TABLE test_data (
 value VARCHAR(25) NOT NULL PRIMARY KEY
);


/*
Multi-line
comment
*/

-- Multi-statement PostgreSQL function
CREATE FUNCTION AddData() RETURNS INTEGER
AS $$
   BEGIN
    INSERT INTO test_data (value) VALUES ('Hello');
    RETURN 1;
  END;
$$ LANGUAGE plpgsql;

SELECT *  INTO TEMP adddata_temp_table FROM AddData() ;

-- Single-statement PostgreSQL function
CREATE FUNCTION add(integer, integer) RETURNS integer
   LANGUAGE sql IMMUTABLE STRICT
   AS $_$select $1 + $2;$_$;

-- Placeholder
INSERT INTO ${tableName} (name) VALUES ('Mr. T');

Limitations

• No support for psql meta-commands with no JDBC equivalent like \set
• Clean does not remove objects created by extensions. It is therefore highly recommended to create your extensions using CREATE EXTENSION IF NOT EXISTS in order to be able to clean and (re-)migrate your schemas at will.
• No support for cleaning referenced large objects in pg_largeobject (Issue 1934)

Feature support for check command

Support for the check command on PostgreSQL databases is currently ongoing. Basic support for the following object types has been implemented.

• Aggregates
• Domains
• Enums
• Foreign Keys
• Functions
• Indexes
• Materialized Views
• Procedures
• Schemas
• Sequences
• Tables
• Triggers
• Views
