We are using a business management system that is using Foxpro databases and we want to be able to sync some information from those tables to PostgreSQL for some other things that we are doing apart from the management system.
I am wondering what the best way is to sync data from Foxpro (.dbf) databases to PostgreSQL-9.4.
I tried to use the Foreign Data Wrapper inside of PostgreSQL to connect with an ODBC connection but I couldn't get it to work.

I would like to develop a ER diagram using DBeaver (Eclipse plugin) for a database that doesn't yet exist. Also, the database server doesn't exist.
Can DBeaver be used to develop a ER diagram without connecting to an existing database server? I can only find documentation for working with an existing database or connecting to an existing database server.
Nope, sorry.
DBeaver tools are always associated with the current connection.
For example, in the ERD when adding tables, DBeaver often sends requests to the database of foreign keys.
You can use standard sample SQLite database in DBeaver for experiments.
How to maintain Postgres to Oracle data synchronized?
Currently we are trying to mimic the Oracle to Oracle database link but with Oracle to Postgres. I know that we can add FDW wrappers to connect but the latency is huge.
I have also checked AWS DMS process but it has lot of data type issues when data load and synchronization from Oracle to Postgres happens.
Can someone tell a better way?
Can someone tell me the difference between pgAdmin and postgreSQL? Are both of them one in the same? I can't draw a ER diagram in pgAdmin but was wondering if it's possible in postgreSQL?
Once I downloaded the postgreSQL it automatically downloaded the pgAdmin and the postgreSQL database is not in sight.
The PostgreSQL is a database engine implementing SQL standards. It usually listen as a server on a network tcp port to provide its abilities.
The pgAdmin is a sort of client. You are able to manipulate schema and data on an instance or multiple instances of PostgreSQL engines.
The MS Windows instalation package consists of both PostgreSQL server and PgAdmin client. So far right after the instalation you are able to manage your databases.
PostgreSQL (pronounced as post-gress-Q-L) is an open source relational
database management system ( DBMS ) developed by a worldwide team of
volunteers. PostgreSQL is not controlled by any corporation or other
private entity and the source code is available free of charge.
The pgAdmin package is a free and open source graphical user interface
administration tool for PostgreSQL, which is supported on many
computer platforms.
phpPgAdmin is a web-based administration tool for PostgreSQL written in PHP and based on the popular phpMyAdmin interface
originally written for MySQL administration
Hope you can understand now it well!!
I have got a sql file where is configured a database in PostgreSQL technology. I created a database from sql file but from code it is hard to understand action/connecting between the tables. Is it some tool which show all the connections between tables for PostgreSQL?
pgDesigner
Data Architect
Datastudio
DbDesigner fork
DbSchema

DeZign for Database
Please take a look to this list of tools.
Suppose I have multiple Oracle databases in the same server. Now I want to connect to particular database and query a table just like SQL Server 2008. How to start particular Oracle database?
If you are using SQL*Plus, the most common syntax for opening a connection is
sqlplus user_name/password#tns_alias
In this example TNS_ALIAS is the TNS alias for the particular database you want to connect to (most likely "XE" based on your followups to inium's answer). If you want to connect to a different database, you would need to specify a TNS alias for that specific database.
Note that since you are coming from a SQL Server background, the SQL Server definition of a database is rather different than the Oracle definition. What SQL Server calls a database is similar logically to what Oracle calls a schema (and similar physically to what Oracle calls a tablespace). So when you're dealing with Oracle, it's much more common to have many schemas in a single database than to have a large number of databases on a server. This is particularly true if you're using the Express Edition (Oracle XE) where you're generally limited to one database per machine.
go to cmd and type sqlplus <database-name>/<database-password>
You can use SQL Developer, it's similar to SQL Enterprise Manager 2005. Just create a new connection using the db user name and password.
