and the attached chart. (v26 is with all patches applied, including the JSON_TABLE one whose grammar has not yet been fully tweaked.) So, while the jump from v26 is not a trivial one, it seems within reasonable bounds. For example, the jump between 13 and 14 looks worse. (I do wonder what happened there.) -- Álvaro Herrera 48°01'N 7°57'E — https://www.EnterpriseDB.com/ "Cada quien es cada cual y baja las escaleras como quiere" (JMSerrat)
