Hi Karol.
I checked gstat and made a manual sweep of the database, but the problem persists.
There are some things I’m finding odd :
-The query brings 4791 records total
-Always on record 4000, it hangs and delays for 15 seconds
-If I manually remove record number 4000, the same thing happens (the “next” record 4000 also hangs the query)
-If I limit the query to just one record short of the total, “SELECT FIRST 4790”, the slow down DOES NOT happen, query runs fine
-I tried, then, removing the last record from the table, so that my new total is 4790, but that didn’t work, the unpaginated query still hangs at record 4000
