• Unify UTC/local timestamp ARRAY typing across JDBC, CAST, materialization, and JSON

• COALESCE does not promote numeric arguments to their common type (CASE does)

• Session time zone reads the user.timezone property and ignores TimeZone.setDefault, unlike java.sql conversions

• Promoting a UTC-adjusted TIMESTAMP to WITH TIME ZONE shifts the instant across DST (ARRAY[ts, CURRENT_TIMESTAMP])

• TIME(6) values are truncated to milliseconds before JSON serialization

• Unary sign on REAL widens the result to DOUBLE (-CAST(1.1 AS REAL) = -1.100000023841858)

  Alipsa/JParq#516 · Filter by author perNyfelt opened on Nov 9, 2026

• CAST(... AS FLOAT(p)) ignores the precision: FLOAT(53) is single-precision REAL

• GROUPING() outside a grouped query is accepted for empty inputs and otherwise fails as an 'Unsupported function'

• Qualified operands prevent matching computed GROUP BY expressions in ORDER BY

  Alipsa/JParq#512 · Filter by author perNyfelt opened on Nov 9, 2026

• HAVING reads a SELECT alias instead of rejecting an ungrouped input column with the same name

  Alipsa/JParq#511 · Filter by author perNyfelt opened on Nov 9, 2026

• ORDER BY a SELECT alias re-evaluates nondeterministic expressions, so rows are not sorted by the returned value

• Correlated references to case-colliding Parquet columns return the wrong column or NULL instead of an ambiguity error

  Alipsa/JParq#508 · Filter by author perNyfelt opened on Nov 8, 2026

• Qualified references to SELECT-list aliases resolve as table columns (m.alias)

• Invalid connection property values are silently accepted or reported without SQLState

  Alipsa/JParq#502 · Filter by author perNyfelt opened on Nov 8, 2026
