Known issues

When you connect to your database, vsql can show the following message:

{{Bad terminal type: "vt100". Will assume vt100.}}

This message can be safely ignored.

JDBC complex types return NULL arrays as empty arrays. For example, when executing this SQL statement: SELECT ARRAY[null,ARRAY[1,2,3],null,ARRAY[4,5],null] as array;

The array column the server returns will be: [[],[1,2,3],[],[4,5],[]]

Because of the null values in the string literal, it should return this value: [null,[1,2,3],null,[4,5],null]

This is a work around to a limitation in Simba.

Under special circumstances, a sequence of statements to create and drop Python libraries fails. For example, the following session statements attempt to create Python libraries lib1 and lib2:

CREATE LIBRARY lib1 AS :lib1_path DEPENDS :numpy_path LANGUAGE 'Python'; DROP LIBRARY lib1; CREATE LIBRARY lib2 AS :lib2_path DEPENDS :sklearn_path LANGUAGE 'Python';

Here, lib1 is a Python library that imports module numpy, while lib2 imports module sklearn, which relies on numpy. After lib1 is dropped, the CREATE LIBRARY statement for lib2 fails.
