sqlbuilder generates multiple "limit" and "offset" clause when invoke ToSqlBuilder multiple times

[HengzheLi]

I use postgres dialect sqlbuilder to generate customized sql. The .Skip() and .Take() is used in my sqlbuilder and found that a new "limit" and "offset" clause is generated as long as .ToSqlBuilder been invoked. If I invoke .ToSqlBuilder twice, there will be two paires of "limit" and "offset". If I invoke .ToSqlBuilder() three times. There will be three pares.

Seems it's a bug, I may fix this if I have a time, it's long time from contributing in YesSQL ;)
