Ok, check in which schema PostGIS operators/functions have been defined, then
</div>
<div>
use fully qualified names of the functions in your UDF.

Ok, as I told befire lambda functions should rely on RDS instances. Once you open a connection
</div>
<div>
to the DB through psycopg, enable the Postgis extension with
<br>
<br>
</div>
<div>
cur.execute("CREATE EXTENSION postgis")
</div>
<div>
<br>
</div>
<div>
then try to run your UDF.

Hi Alexander,
</div>
<div>
<br>
</div>
<div>
can you add further details (snippet of code, etc.) about this?
<br>
<br>Never tried doing this, but AFAIK AWS lambda runs on preconfigured RDS environments,
</div>
<div>
maybe it's just enough to include the CREATE EXTENSION.
</div>
<div>
<br>
</div>
<div>
Giuseppe.

I'm trying to create a service to invoke Postgres UDFs that utilize PostGIS
<br> functions via an AWS lambda function. The error I get is as if the PostGIS
<br> extension is not installed. Has anyone encountered this before?
<br>
<br> Thanks
