DBeaver: `NumberFormatException` when importing data into table with boolean column

[hlcianfagna]

create table repro (flag BOOLEAN);

Then create a .csv file and try to import it from DBeaver with the default "Data load settings" with "Skip bind values during insert" not selected

flag
0

In CrateDB this will fail with

NumberFormatException in java.base/java.math.BigDecimal.<init>(BigDecimal.java:703).CXX000.FSQLExceptions.java.ResToCrateException.L152.Wio.crate.exceptions.SQLExceptions.esToCrateException(SQLExceptions.java:152)

in PostgreSQL it works (DBeaver also succeeds if the column is INT instead of BOOLEAN or if we select the option to skip binding)

I can get the same stack trace in Java if I use a setBigDecimal against a PreparedStatement instead of a setBoolean , however this fails also against pgqsl while DBeaver works against pgsql.

So perhaps this something about pg_type not having composite type entries for the tables or about pg_description not having an entry for the boolean data type?

Hi @hlcianfagna. Thanks for your report.

Can I humbly ask you to evaluate the problem closer, maybe together with @surister, @seut, or @proddata, and maybe derive or transfer this issue into crate/crate, also tagging it with tool: DBeaver, when applicable?

I did a quick test, this still occurs with the latest version of DBeaver and the latest nightly of CrateDB.
