In PostgreSQL, you can retrieve the schema details of a specific table by querying the information_schema.columns view or by using the pg_catalog.pg_attribute table. Here’s an example SQL query using information_schema.columns:

sqlCopy
SELECT 
    column_name,
    data_type,
    character_maximum_length,
    is_nullable,
    column_default
FROM 
    information_schema.columns
WHERE 
    table_name = 'your_table_name'
ORDER BY 
    ordinal_position;

This query will provide details such as column names, data types, maximum length, whether the column allows NULL values, and any default values.

Be sure to replace 'your_table_name' with the name of the table you want to inspect.
