Hi !While developing a Java GUI front-end to Postgresql I've faced the
next problem:
I want my program to 1. list all the available tables in the database 2. Show the structure of the
chosentable.1.The first task is OK,it can easily be done by inspecting the PG_TABLES2. Please tell me how can I
determinethe structure of the table(field names and types) using Postgres JDBC Driver in order to
complete the second task.
Thank you in advance for your reply.

You might want to inspect the code for psql to see how this is done.
"\d" and "\d tablename" seem to do what you want.
