liquibase postgresql creating functions - postgresql

Question

I am using liquibase to create triggers for postgressql database. Below is the syntax which I use in liquibase
<?xml version="1.0" encoding="UTF-8"?>
<databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog
http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.1.xsd">
<changeSet id="1" author="yc14ik1">
<createProcedure catalogName="cat" dbms="postgresql"
encoding="utf8" procedureName="UPDATE_LAST_ROW_CHG_TS()" relativeToChangelogFile="true" schemaName="sub">
CREATE OR REPLACE FUNCTION UPDATE_LAST_ROW_CHG_TS() RETURNS trigger
LANGUAGE plpgsql
AS $$
BEGIN
NEW.LAST_ROW_CHG_TS = NOW();
RETURN NEW;
END;
$$;
</createProcedure>
<sql></sql>
</changeSet>
When this procedure is executed in Jenkins Job, I get this error
Unexpected error running Liquibase: ERROR: language "plpgsql" does not exist
Hint: Use CREATE LANGUAGE to load the language into the database. [Failed SQL: CREATE OR REPLACE FUNCTION UPDATE_LAST_ROW_CHG_TS() RETURNS trigger
LANGUAGE plpgsql
AS $$
BEGIN
NEW.LAST_ROW_CHG_TS = NOW();
RETURN NEW;
END;
$$;]
Build step 'Execute shell' marked build as failure
Notifying upstream projects of job completion
Warning: you have no plugins providing access control for builds, so falling back to legacy behavior of permitting any downstream builds to be triggered
Can some one help me how can I fix this problem ?

I set up mine differently and it works just fine.
<databaseChangeLog
xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ext="http://www.liquibase.org/xml/ns/dbchangelog-ext"
xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.1.xsd
http://www.liquibase.org/xml/ns/dbchangelog-ext http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd">
<changeSet author="l" id="UPDATE_LAST_ROW_CHG_TS" runOnChange="true">
<createProcedure catalogName="UPDATE_LAST_ROW_CHG_TS"
dbms="postgresql"
encoding="utf8"
path="../files/UPDATE_LAST_ROW_CHG_TS.sql"
procedureName="UPDATE_LAST_ROW_CHG_TS"
relativeToChangelogFile="true"
schemaName="public"></createProcedure>
</changeSet>
</databaseChangeLog>
from there you put all the sql inside a .sql file referenced in the path attribute.
I dont know that your way wont work but it seems odd to me that you have empty tags towards the bottom. Maybe you meant for those to wrap your sql function?
Anyways I know the example above will work if liquibase is configured and ran properly.
