In order to re-calculate min/max values for groups where the min or max value is deleted, we need the view query definition in string form. However, pg_get_viewdef cannot be used for this purpose because IMMV's defenition is in pg_ivm_immv but not pg_rewrite. Therefore, we have to convert query definition in pg_ivm_immv to query definition string. We can use pg_get_querydef in PG15, but we cannot in PG14 or earlier, so we use codes in ruleutil.c copied from PG13 or PG14 depending versions. |
