Bug #14392

Updated by Fran├žois ARMAND over 5 years ago

With a very very large list of groups in a rules, the historization (part of policy generation) fails because we have a pkey constraint on table rulesgroupjoin (rules id + serialization of groups of rules)  
 However, this pk creates a btree, that cannot index long text - error is 

 
 <pre> 
 ERROR:    index row size 3528 exceeds maximum 2712 for index "rulesgroupjoin_pkey" 
 ASTUCE : Values larger than 1/3 of a buffer page cannot be indexed. 
 Consider a function index of an MD5 hash of the value, or use full text indexing. 
 </pre> 

 dropping the pkey solves the issue 

 
 <pre> 
 alter table rulesgroupjoin drop constraint rulesgroupjoin_pkey; 
 </pre> 

 recreating an index is still necessary for correct perf of historization though: 

 <pre> 
 CREATE INDEX rule_id_group on rulesgroupjoin (rulePkeyId); 
 </pre>
