Hi Dylan,

In newer versions of PostGIS we standardised on the form of the 
ST_As*ML() functions so that they are all of the form (version, 
geometry, precision). However, for older functions that didn't have the 
version parameter by default, there should be a PL/PGSQL wrapper 
function that acts as a compatibility layer.

So as Regina suggested, it sounds to me as if something went wrong as 
part of a database upgrade from an earlier PostGIS version so that the 
wrapper function is not present in your new database.


HTH,

Mark.
