No. The text files are smaller than the postgresql \data folder, especially if your \data\pg_log folder is full of log files. My DB is about 1.6GB (no log files) and exports to approximately 435MB.
Logging:
I would suggest you turn off logging on your new SQL installation as well as these other performance improvements - Top 10: HEM performance increase tips
To turn off logging, follow these instructions. This is the first thing I do anytime I install SQL for someone.
- Start > My Computer > Tools > Folder Options > View > UnCheck 'Hide Extensions for known file types' > OK
- C:\Program Files\PostgreSQL\data\postgresql.conf > Right-Click > Open With.. > NotePad > Check 'Always use this program'
- Scroll about half way down to ~Lines 245 - 260:
- The last line of this block of code, for the 'logging_collector', must be changed from On to Off.

log_destination = 'stderr' # Valid values are combinations of

# This is used when logging to stderr:
logging_collector = off # Enable capturing of stderr and csvlog

- Start > My Computer > C:\Program Files\PostgreSQL\data\pg_log, or C:\Program Files (x86)\PostgreSQL\data\pg_log, if you have 64 bit Vista. Delete all files in that folder. And it might be a good idea to empty your recycle bin at that point, or use a 3rd party utility like CCleaner to clean up all your junk/temporary files. You want to do this before you get to the vacuum and defrag process.
