Hello hackers,
Here is a summary of what was implemented over the summer in PL/Julia:
1. Added support for more datatypes as input and output:
NULL, boolean, numeric types, composite types, arrays of base types can now be passed as input arguments to PL/Julia functions. Users can also return the above, or sets of the above from PL/Julia UDFs.
2. Added trigger support - users can write trigger functions in PL/Julia
3. Added event trigger support
4. Added support for the DO command
5. Added functions for database access from PL/Julia:
spi_exec(query, limit) and spi_exec(query) for SQL-statement execution,
spi_fetchrow(cursor) and spi_cursor_close(cursor) to return rows and to close the cursor respectively,
spi_prepare(query, argtypes) to prepare and save an execution plan and
spi_exec_prepared(plan, args, limit) to execute a previously prepared plan.
Currently the extension works for version 13 and Julia versions >= 1.6 (Thanks to Imre Samu for testing!)
I hope you find it interesting.
Regards,
Konstantina
