Bitcoin PostgreSQL

In a previous post I described a simplistic schema to store the Bitcoin blockchain in PostgreSQL. In this post I'm investigating pushing the envelope with a bit of C programming. The Missing Functionality. Postgres cannot do certain things required to fully handle transactions. The missing functionality is (at least) Bridge between Bitcoin and PostgreSQL. Coinbridge connects the Bitcoin daemon (bitcoind) and a local PostgreSQL database. It listens for transaction confirmations and automatically updates a transactions table in your database. Includes a payment method which uses free, instant Bitcoin transfers between accounts in the same wallet, and standard Bitcoin transactions otherwise. Also includes a comprehensive wrapper for Bitcoin's JSON-RPC functionality BTC closing price in USD over the last seven years. Using PostgreSQL, we've queried BTC's prices at 2-week intervals, analyzing the rates for USD exchanges. (Note that time_bucket and last in this query are special TimescaleDB time-series data analysis functions not in PostgreSQL. For this analysis, we used PostgreSQL and TimescaleDB to analyze market data about Bitcoin, Ethereum and 4196 other cryptocurrencies, and used Tableau to visualize our results. This post shares many high level insights about the crypto market since its inception and during recent years

I'm not familiar enough with postgres functions to say if that's possible. I assume it would be, but I would avoid doing it for two reasons 1) iif() is an oddball for RDBMSs. Every RDBMS under the sun uses CASE. To make your SQL more standard-ish switching to CASE would be a good idea. 2) I'm betting a UDF would be slower than something as deeply entrenched in RDBMS logic as a CASE Browse 1 Remote Amazon Web Services Bitcoin Postgres Senior Typescript Job in June 2021 at Opennode working as a Senior Node.js Backend Engineer.

Client authentication is controlled by a configuration file, which traditionally is named pg_hba.conf and is stored in the database cluster's data directory. (HBA stands for host-based authentication.)A default pg_hba.conf file is installed when the data directory is initialized by initdb.It is possible to place the authentication configuration file elsewhere, however; see the hba_file. To avoid breaking references and/or rules during design time and when exporting the model to PostgreSQL, pgModeler validates models from time to time.
