I have installed PostgreSQL server on a Windows Server 2008 server and I need to write a more complex parser than the default one in PostgreSQL. Searching on internet i found this example: http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/docs/HOWTO-parser-tsearch2.html where the parser is written in C language. I would know if can I write the parser in another language (Java, I'm very poor in C)? And, if I can, what kind of file would contain the functions of the parser (a dll file, a class file). The last question is: in that example are used some functions (PG_GETARG_POINTER, PG_GETARG_INT32, and so on) that seem PostgreSQL specific functions; which functions can I use in java?
you'd better learn C if you want to do this. those functions are part of the tsearch parser API, which is a machine level API interface, Java would be a huge uphill battle of fighting JNI stuff to get working, and then you'd be attaching the whole huge bloated JVM to the side of postgresql to implement this.
