Summary: in this tutorial, you will learn how to use the psql tool and information_schema to describe tables in PostgreSQL.. TL;DR;: keep the search_path variable set to its default of public, name schemas other than public explicitly within Table definitions. And plenty of people, like Natan who remarked prior to you, want to avoid moving functions and/or views from old extensions in the event that they are starting with a … Disagree.

Therefore, it is not possible to store very large field values directly. The table that is divided is referred to as a partitioned table.The specification consists of the partitioning method and a list of columns or expressions to be used as the partition key.. All rows inserted into a partitioned table will be routed to one of the partitions based on the value of the partition key. One slight but critical part is missing and I am wondering if you could add it. CREATE TABLE temp_table_1 (id SERIAL); -- A dynamic table is created INSERT INTO inventory VALUES (1, 'temp_table_1', '2020-10-07 10:00:00'); -- We add it into the inventory Then you could get advantage of pg_tables to run something like this to get existing table creation dates: Setting up PostgreSQL. The best I could come up with would be to do a select something like this: SELECT * FROM pg_attribute WHERE attrelid=; The problem I'm running into however, is that given a table name, there PostgreSQL offers a way to specify how to divide a table into pieces called partitions. For each column we can set the name, the type, and the constraints we want each column to have. : Install PostgreSQL; Use your favorite package manager to install PostgreSQL, e.g. list of tables, but there doesn't seem to be any built in method for retrieving a table definition. Is there a way that I can make a metadata-sheet that lists all the available tables from a postgresql-database, so users can see documentation of the tables? The order of retrieval is based on the size (cardinality) of the table. select TABLE_NAME, INDEX_NAME, NON_UNIQUE, COLUMN_NAME from INFORMATION_SCHEMA.STATISTICS where TABLE_SCHEMA = 'my_schema' order by TABLE_NAME, INDEX_NAME, SEQ_IN_INDEX It seems that the STATISTICS table of INFORMATION_SCHEMA is a SQL Server extension. Cardinality is used for equi-joins. ... in the table during metadata creation. If you have been using MySQL, you typically use the DESCRIBE statement to find the information on a table.. PostgreSQL does not support the DESCRIBE statement.However, you can query the information on columns of a table in a couple of ways. Finally, on the “metadata.create_all(engine)” line we create our new table in the database. How can I do the equivalent in PostgreSQL? To use this Apache Druid extension, make sure to include postgresql-metadata-storage as an extension.. To overcome this limitation, large field values are compressed and/or broken up into multiple physical rows.
