Error in Pgsql
**To Reproduce**
Steps to reproduce the behavior:
1. Go to 'dotnet Miningcore.dll -c config.json'
2. Start miningcore normally
4. Right after I get the error in the database
`[E] [StatsRecorder] Npgsql.PostgresException (0x80004005): 42703: column "poolid" does not exist`

Right after the miner shares a share I get the following message on the screen.

`[ShareRecorder] System.InvalidCastException: Cannot write DateTime with Kind=UTC to PostgreSQL type 'timestamp without time zone', consider using 'timestamp with time zone'. Note that it's not possible to mix DateTimes with different Kinds in an array/range. See the Npgsql.EnableLegacyTimestampBehavior AppContext switch to enable legacy behavior.`

And in the pgsql log I get

`miningcore@miningcore ERROR:  COPY from stdin failed:
miningcore@miningcore STATEMENT:  COPY shares (poolid, blockheight, difficulty, networkdifficulty, miner, worker, useragent, ipaddress, source, created) FROM STDIN (FORMAT BINARY)`

Hello again.
I managed to run Miningcore but now I get some errors from pgsql.

I did the process as instructed by README.md.
Even so I tried many times, and I can't find the problem again (noob)

there are all tables and columns correctly in the BD, however the same error occurs.

I looked in many places on the internet about the tables and columns, and also about the timestamp, but without success.
If you can help, thank you immensely.
Sorry but I don't think where I can change this.
