Issues with Concurrency for PostgresPersister StartAutoLoad and StartAutoSave

[adrian-burlacu-software]

Hi everyone,

I am building an open source DB engine backed by TinyBase.
Stark-DB Rx branch

I have everything mostly working. There is just a small-looking bug that I found when testing my engine. It is that I cannot read and write at the same time with PostgresPersister.startAutoLoad and startAutoSave. Basically the reads wipe out my writes sometimes.

I know about CQRS(and event sourcing, and have heard of CRDT) so I am not fully surprised, but I would like to know if this is a bug in TinyBase or if there is a quick fix that I can implement on my side.
Here is the line that if I comment out all my tests stop losing data.

Did some more testing

1. even if I set the autoLoadIntervalSeconds on the persister to very low 0.1 or very high 60 the issue persists.
2. if I make my own interval this issue is not apparent although with a 100ms interval i can make a test fail.

Due to these findings I think it's a bug in TinyBase...
