Connecting to Postgres using Dremio Community 4.01, I get this error:
UnsupportedOperationException: BigDecimal scale must equal that in the Arrow vector: 13 != 10
This is with a query:
select * from users
select *, 1 from users
This suggests it’s not an issue interpreting a numeric (i.e. decimal) field.
PostgreSQL 9.6.15 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-36), 64-bit
