hi,
PGV14, client use PGJDBC driver and prepared statements, when a table
"alter table alter column type ..." changes done, a lot of JDBC clients got
this error "cached plan must not change result type". when a JDBC client
got this error first time after the DDL schema change, JDBC driver will
clear this caching-plan and following same SQL statement got parsing again
and new cached plan right?
How to avoid this issue when DDL schema changes ?
Thanks,
James
