NodeJS/PostgreSQL Errors - node.js

Question

I am setting up a Node app that has connections to multiple databases. I am using a map to create Pools for all my databases as such:
const stnPool = new Map();
async function getOtherDb(stnName){
if(!stnPool.has(stnName)){
stnPool.set(stnName, new Pool({
host: 'localhost',
database: stnName.toLowerCase(),
user: USERNAME,
password: PASSWORD,
port: 5432,
max: 2000,
idleTimeoutMillis: 0,
connectionTimeoutMillis: 0,
}))
}
return stnPool.get(stnName);
}
PostgreSQL currently has 10 'station' databases. I have 10 remote servers that connect to my server and upload data every 3 seconds. I also have an X number of clients that connect to view the uploaded data in realtime. Bot Server and Client connections connect to upload/request data via Websockets.
To establish aan query a Pool connection:
var uvDb = await db.getOtherDb("wx_uv")
if( uvDb != -1 ) {
const dbT = await uvDb.connect()
... do various db queries ...
dbT.release()
}
After a few hours of getting Server uploads and Client requests I get this error:
/.../node/node_modules/pg-protocol/dist/parser.js:287
const message = name === 'notice' ? new messages_1.NoticeMessage(length, messageValue) : new messages_1.DatabaseError(messageValue, length, name);

}
Anyone have any ideas on what causes this?
=======UPDATE=======
Tried adding a try/catch to release the connection as well:
if( uvDb != -1 ) {
const dbT = await uvDb.connect()
try{
... do various db queries ...
dbT.release()
} catch (err) {
dbT.release()
}
}
But now I get other errors...
"error: lost connection to parallel worker"
"error: parallel worker failed to initialize"
