Using PostgreSQL UUID column type in Propel as keys - not properly escaped in relation insert

[Kedarius]

I am trying to use PostgreSQL UUID column type as primary and foreign key. My schema looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<database name="videoarchive" defaultIdMethod="none">
   <table name="video" phpName="Video">
    <column name="id" type="varchar" required="true" primaryKey="true" sqlType="uuid" />
    <column name="title" type="varchar"  required="true" />
    <column name="description" type="varchar"  required="true" />    
    <column name="channel_id" type="varchar" required="true"  sqlType="uuid" />
    <foreign-key foreignTable="channel" phpName="Channel" refPhpName="Video">
      <reference local="channel_id" foreign="id"/>
    </foreign-key>
  </table>
  <table name="channel" phpName="Channel">
    <column name="id" type="varchar" required="true" primaryKey="true" sqlType="uuid" />
  <column name="title" type="varchar"  required="true" />
    <column name="description" type="varchar"  required="true" />        
  </table>
</database>

Creating and saving objects works fine:

 $c = new Channel();
 //set all properties of Channel object
 $c->setDescription('xxxxx');
 $c->save();

However when I try:

 $q = new ChannelQuery();
 $firstChannel = $q->findPK('be8d37ca-db94-4070-88e7-4a6690410a2e');
 $video=new Video();
 //set all properties of Video object
 $video->setChannelId($firstChannel);
 $video->save();

I do get SQL errors, because the channelId is not properly quoted:

[2018-09-13 00:48:04] defaultLogger.ERROR: SQLSTATE[22P02]: Invalid text representation: 7 ERROR: invalid input syntax for uuid: "Id: be8d37ca-db94-4070-88e7-4a6690410a2e Title: 'xxx' Description: 'xxx' " [] []

However
$video->setChannelId($firstChannel->getId());
works fine.

Propel is installed from composer ( "propel/propel": "~2.0@dev", ), engine is PostgreSQL and PHP 5.6.
Just to be thorough I even tried changing type to binary in all UUID columns to no avail.

Is this still relevant or can it be closed?

Sorry, the project where I needed it kinda died and I have no ability to check it now.
