RE: Sudden database error with COUNT(*) making Query Planner crashes: variable not found in subplan target list - Mailing list pgsql-hackers

Dear David,

Thank you for taking time on this issue.

Here is the detail of the table (I have anonymized it on SO, this is its real name):

\d logistic_site
                                          Table « public.logistic_site »

Additional information:
When trying to read the SQL related query for this table in PgAdmin4 I also have the error message popping up and the I
getno SQL. So maybe the problem resides in a deeper function the Query Planner and SQL generator functions rely on. 
 

Don't hesitate to ask for more information.

Best regards,
