* Workaround for events with NUL char, touch up error loop
This fixes an error where some events would not save
due to having the 0x00 character which errors in postgres
this adds a line to replace it with empty text
Hitting that kind of event put us in an infinite error loop
so this change makes a number of changes to prevent similar loops
the showcase example is a negative counter,
this is not realistic in the real world but works for unit tests
These error loop fixes seek to esablish the cases where we clear the buffer
Some logic is removed from the outer loop, with the idea that
ensure_connection will better distinguish flake
* From review comments, delay NUL char sanitization to later
Use pop to make list operations more clear
* Fix incorrect use of pop
