Describe the issue
I get a NumberFormatException when fetching a PGInterval with value less than 1 millisecond.

Driver Version?

OS Version?
Manjaro linux with kernel 5.3.11-1-MANJARO

PostgreSQL Version?
11.6

To Reproduce

• create table foo(bar interval)
• insert into foo(bar) values ('0.0001 seconds')
• Fetching the row as PGInterval will throw exception

Expected behaviour
Get a PGInterval instance with 100 microseconds.
