Change default precision and scale for NUMERIC fields

smontiel

We recently noticed that some operations such as division, square root or power involving decimals would sometimes produce a column with a NUMERIC field when not specified by a table schema. The NUMERIC type is fine with us, but some fields are being output with values for precision and scale outside of the PARQUET standard for exporting data out of Vertica.

We can CAST the fields, but we were hoping there was a way to change the default behavior of Vertica by not going above the 38 digits of precision or the 9 digits of scale.
