Tcl is a surprisingly simple language.

Having said that, I should point out that solving complex problems is not necessarily easier in Tcl than in other languages, you just have fewer syntactic rules to remember. Tcl is not a panacea, just a really nice little language.

The libpgtcl library fits into Tcl very nicely. If you want to toss together a PostgreSQL client application quickly, explore Tcl and libpgtcl.
