Redshift Federated Query Error 25101

Hello everyone,

I discovered a problem during a Redshift Spectrum SELECT query that works as expected when it's ran inside the RDS (Postgres) DB.

The query is like the following:

SELECT MIN(column) FROM table;

When ran inside the RDS, the result is correct, when ran via Redshift Spectrum it raises the following exception:

SQL Error [XX000]: ERROR: Decimal input parse error
  Detail: 
  -----------------------------------------------
  error:  Decimal input parse error
  code:      25101
  context:   str:0.5507626528024723909068
  query:     10256
  location:  federation_fetchers.cpp:194
  process:   query0_121_10256 [pid=8648]
  -----------------------------------------------

The data type is set to NUMERIC in the RDS DB. Please, notice there is no 0.5507626528024723909068 value in the table.

I can't find any similar question anywhere and I would be really grateful if anyone had any advice on this. Thank you in advance!
