OS command injection (CWE-78) vulnerability in pgAdmin 4 Import/Export query export.

User-supplied input was interpolated directly into a psql copy metacommand template without sanitization. An authenticated user could inject ") TO PROGRAM 'cmd'" to break out of the copy (...) context and achieve arbitrary command execution on the pgAdmin server, or ") TO '/path'" for arbitrary file write. Additional fields (format, on error, log verbosity) were also raw-interpolated and exploitable.

Fix adds a parens-balance parser modeled on psql's strtokx tokenizer, allow-lists format/on error/log verbosity, rejects null bytes in the query, and tightens type and gating checks.

This issue affects pgAdmin 4: before 9.15.
