 Security tablesCharacter Sets and Collations 

Plugin tables are tables — or views — created for or by various plugins to the Firebird engine.The standard plugin tables have the prefix PLG$.

Important

The plugin tables do not always exist.For example, some tables only exist in the security database, and other tables will only be created on first use of a plugin.

This appendix only documents plugin tables which are created by plugins included in a standard Firebird 5.0 deployment.

Plugin tables are not considered system tables.
Note
Profiler table names are plugin-specific

The tables listed in this appendix for the profiler (starting with PLG$PROF_) are created by the Default_Profiler plugin.If a custom profiler plugin is created, it may use different table names.
